Hence, option E is correct.
Explanation :
I. 2x^{2} + 11√3x + 45 = 0
2x^{2} + 6√3x + 5√3x + 45 = 0
2x(x + 3√3) + 5√3 (x + 3√3) = 0
(2x + 5√3)(x + 3√3) = 0
II. y^{2} + 8√3y + 45 = 0
y^{2} + 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
Therefore, x ≥ y
Hence, option C is correct.

Quadratic Equation for Bank Exam:
Quadratic Equation questions with explanations will help the aspirants to score more marks in Banking exams like IBPS Clerk, IBPS PO, SBI PO, SBI Clerk and other competitive exams which also increases the chances of being selected in these exams. Smartkeeda guides and provides you to lots of fully solved quadratic equation practice questions and answers with explanation while on other hand Testzone helps Candidates preparing for banking and other competitive exams can access their ability here , accuracy and speed through quadratic equation quizzes.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. x^{2} – 17.5x + 69 = 0
II. 2y^{2} – 25y + 78. = 0
II. 2y^{2} – 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. x^{2} – 17.5x + 69 = 0
x^{2} – 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. 2y^{2} – 25y + 78 = 0
2y^{2} – 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.
Hence, option E is correct.
2. I. x^{2} + 6x – 112 = 0
II. y^{2} + 22y + 112 = 0
II. y^{2} + 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. x^{2} + 6x – 112 = 0
x^{2} + 14x – 8x – 112 = 0
x (x + 14) – 8(x + 14) = 0
(x + 14)(x – 8) = 0
x = 8, – 14
II. y^{2} + 22y + 112 = 0
y^{2} + 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
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. 2x^{2} + 11√3x + 45 = 0
II. y^{2} + 8√3y + 45 = 0
II. y^{2} + 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. 2x^{2} + 11√3x + 45 = 0
2x^{2} + 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. y^{2} + 8√3y + 45 = 0
y^{2} + 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. x^{2} + 9x + 20 = 0
II. y^{2} + y – 12 = 0
II. y^{2} + 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. x^{2} + 9x + 20 = 0
x^{2} + 5x + 4x + 20 = 0
x(x + 5) + 4(x + 5) = 0
(x + 4)(x + 5) = 0
x = – 4, – 5
II. y^{2} + y – 12 = 0
y^{2} + 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. 3x^{2}– 243 = 0
II. 12y^{5} + 110y^{4} = 0
II. 12y^{5} + 110y^{4} = 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
I. 3x^{2} – 243 = 0
3x^{2} = 243, x^{2} = 81 , x = ± 9
II. 12y^{5} + 1100y^{4} = 0
12y^{5} = –110y^{4},
Hence, option E is correct.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
For x = – 9, and y = 0 x < y
Therefore, relationship cannot be established
