### Quadratic Equation for Bank PO Exam like SBI PO, IBPS PO, LIC AAO:

The SBI PO and LIC AAO are the examinations which are very popular in India among students. every year millions of students enroll in theses exams but do you know only few of them succeed do you know why? Because these exams are not easy. These exams need solid preparation speed strategy and accuracy on all the topics across all the sections. And one of the important topic which is asked in these exams is Quadratic Equation keep one thing in mind not to see this topic as lightly as it seems.

Let discuss Quadratic equation in detail with the help of examples :

1. I.  x2 – 17.5x + 69 = 0
II.
2y2 – 25y + 78. = 0

A. if x > y
B.  if x ≤ y
C. if x ≥ y
D. if x < y
E. if x = y or relationship between x and y can't be established

Explanation :

I. x2 – 17.5x + 69 = 0

x2  –  11.5x – 6x + 69 = 0

x(x – 11.5)  –   6(x – 11.5) = 0

(x – 11.5)(x  –  6) = 0

x = 11.5, 6

II. 2y2 – 25y + 78 = 0

2y2 – 13y – 12y + 78 = 0

y (2y  –  13) –  6(2y – 13) = 0

(2y – 13)(y – 6) = 0

y = 6.5, 6

For x = 11.5  and y = 6.5, 6     x > y

For x = 6, and y = 6.5, 6         x ≤ y

Therefore, relationship can’t be established

Hence, option E is correct.

2. I. x2 + 6x  –  112 = 0
II.
y2 + 22y + 112 = 0

A. if x > y
B. if x ≤ y
C. if x ≥ y
D. if x < y
E. if x ≤ y or no relationship can be established between x and y.

Explanation :

I. x2 + 6x  – 112 = 0

x2 + 14x  –  8x  – 112 = 0

x (x + 14)  –   8(x + 14) = 0

(x + 14)(x – 8) = 0

x = 8, – 14

II. y2 + 22y + 112 = 0

y2 + 8y + 14y + 112 = 0

y(y + 8) +  14(y + 8) = 0

(y + 8)(y + 14) = 0

y = – 8, – 14

For, x = – 14 and y = – 8

x < y

For, x = – 14 and y = – 14

x = y

But for x = 8 and y =  – 8 and – 14

x > y

Therefore, relationship can’t be established

Hence, option E is correct.

3. I. 2x2 + 11√3x + 45 = 0
II. y2 + 8√3y + 45 = 0

A. if x > y
B. if x ≤ y
C. if x ≥ y
D. if x < y
E. if x = y or relationship between x and y can't be established

Explanation :

I. 2x2 + 11√3x + 45 = 0

2x2 + 6√3x + 5√3x + 45 = 0

2x(x + 3√3) + 5√3 (x + 3√3) = 0

(2x + 5√3)(x + 3√3) = 0

 x = – 3√3, – 5 √3 2

II. y2 + 8√3y + 45 = 0

y2 + 5√3y + 3√3y + 45 = 0

y(y + 5√3) + 3√3 (y + 5√3) = 0

(y + 5√3)(y + 3√3) = 0

y = – 5√3, – 3√3

For x = – 3√3 and y = – 3√3     x = y

For x = – 3√3 and y = – 5√3     x > y

 For x = – 5 √3 and y = – 5√3, – 3√3 x > y 2

Therefore, x ≥ y

Hence, option C is correct.

4. I. x2 + 9x + 20 = 0
II. y2 + y  –  12 = 0

A. if x > y
B. if x ≤ y
C. if x ≥ y
D. if x < y
E. if x = y or relationship between x and y can't be established

Explanation :

I. x2 + 9x + 20 = 0

x2 + 5x + 4x + 20 = 0

x(x + 5) +  4(x + 5) = 0

(x + 4)(x + 5) = 0

x =  – 4,  – 5

II. y2 + y – 12 = 0

y2 + 4y – 3y – 12 = 0

y (y + 4)  –   3(y + 4) = 0

(y + 4)(y  –  3) = 0

y =  – 4, 3

For x =  – 4 and y =  – 4, x = y

For x =  – 4, y = 3 , x < y

For x =  – 5, y =  – 4 or 3 , x < y

Therefore, x ≤ y

Hence, option B is correct.

5. I. 3x2– 243 = 0
II.
12y5 + 110y4 = 0

A. if x > y
B. if x ≤ y
C. if x ≥ y
D. if x < y
E. if x = y or relationship between x and y can't be established

Explanation :

I. 3x2 – 243 = 0

3x2 =  243, x2 = 81 , x = ± 9

II. 12y5 +  1100y4 = 0

12y5 = –110y4,

 y = – 110 = – 9.16 , 0 12

For x = 9, and y =  – 9.16 , 0    x > y

For x =  – 9, and y =  – 9.16,  x > y

For x =  – 9, and y =  0    x < y

Therefore,  relationship  cannot be established

Hence, option E is correct.

II.
54y2 + 87y + 35 = 0

A.x > y
B. x < y
C. x ≥ y
D. x ≤ y
E. if x = y or relationship between x and y can't be established

Explanation :

I. 6x2 – 37x – 35 = 0

6x2 + 5x – 42x – 35 = 0

x(6x + 5) – 7(6x + 5) = 0

(x – 7)(6x + 5) = 0

 x = 7, – 5 6

II. 54y2 + 87y + 35 = 0

54y2 + 42y + 45y + 35 = 0

6y(9y + 7) + 5(9y + 7) = 0

(6y + 5)(9y + 7) = 0

 y = – 5 , – 7 6 9

 Therefore, for x = 7 or – 5 and y = – 5 or – 7 6 6 9

Hence, option E is correct.

2. I. 8x2 – 18√3x + 27 = 0
II. 15y2 – 14√3y + 9 = 0

A.x > y
B. x < y
C. x ≥ y
D. x ≤ y
E. if x = y or relationship between x and y can't be established

Explanation :

I. 8x2 – 18√3x + 27 = 0

8x2 – 12√3x – 6√3x + 27 = 0

4x(2x – 3√3) – 3√3 (2x – 3√3) = 0

(2x – 3√3)(4x – 3√3) = 0

 x = 3 √3, 3 √3 4 2

II. 15y2 – 14√3y + 9 = 0

15y2 – 9√3y – 5√3y + 9 = 0

3y(5y – 3√3) – √3 (5y – 3√3) = 0

(3y – √3)(5y – 3√3) = 0

 y = 1 √3, 3 √3 3 5

 For x = 3 √3, 3 √3 and y = 1 √3, 3 √3 4 2 3 5

x > y

Hence, option A is correct.

II. 9y2 – 30y + 16 = 0

A.x > y
B. x < y
C. x ≥ y
D. x ≤ y
E. if x = y or relationship between x and y can't be established

Explanation :

I. 9x2 – 39x + 40 = 0

9x2 – 24x – 15X + 40 = 0

3x(3x – 8) – 5(3x – 8) = 0

(3x – 8)(3x – 5) = 0

 x = 8 , 5 3 3

II. 9y2 – 30y + 16 = 0

9y2 – 6y – 24y + 16 = 0

3y(3y – 2) – 8 (3y – 2) = 0

(3y – 8)(3y – 2) = 0

 y = 8 , 2 3 3

 For x = 8 and y = 2 3 3

x > y

 For x = 5 and y = 8 3 3

x < y

Therefore, relationship can’t be established

Hence, option E is correct.

10x2 + 35x – 22x – 77 = 0

5x(2x + 7) – 11(2x + 7) = 0

(5x – 11)(2x + 7) = 0

 x = 11 , – 7 5 2

II. 8y2 + 45y + 63 = 0

8y2 + 24y + 21y + 63 = 0

8y(y + 3) + 21(y + 3) = 0

(8y + 21)(y + 3) = 0

 y = – 21 , – 3 8

 For x = – 7 , and y = – 3 2

x < y

 For x = – 11 , and y = -3 5

x > y

Therefore, relationship can’t be established

Hence, option E is correct.

Explanation :

I. x2 + 12x + 35 = 0

x2 + 7x + 5x + 35 = 0

x(x + 7) +  5(x + 7) = 0

(x + 5)(x + 7) = 0

x = – 7, – 5

II. y2 + 9y + 20 = 0

y2 + 4y + 5y + 20 = 0

y(y + 4) + 5(y + 4) = 0

(y + 5)(y + 4) = 0

y = – 5, – 4

For x = – 7 and y = – 5 or – 4

x < y

For x = – 5 and y = – 5, x = y

For x = – 7 and y = – 4

Therefore, x ≤ y

Hence, option D is correct.
