⇒ x^{2} – 10x + 2x – 20 = 0

⇒ x (x – 10) + 2 (x – 10) = 0

⇒ (x – 10) (x + 2) = 0

Then, x = + 10 or x = – 2

⇒ y^{2} – 20y + 99 = 0 [Dividing both sides by 3]

⇒ y^{2} – 11y – 9y + 99 = 0

⇒ y (y – 11) – 9 (y – 11) = 0

⇒ (y – 11) (y – 9) = 0

Then, y = + 11 or y = + 9

So, when x = + 10, x < y for y = + 11 and x > y for y = + 9

And when x = – 2, x < y for y = + 11 and x < y for y = + 9

Hence, option (E) is correct.

Folks, here is a another quiz of Quadratic Equation, so we are going to discuss different kind of Quadratic Equation questions which are frequently asked in SBI clerk pre 2021 Pre Exam, So Quadratic Equation have a lot of chance to appear in SBI Clerk Pre2021.

First of all we discuss different kind of Quadratic Equation for SBI Clerk Pre 2021 like New pattern based Quadratic Equation Question and Answer that are now being asked in the exams are high level and it can be based on root based quadratic equation and general Quadratic Equation, find out the root values and then compare them and last but not the least Shri Dharcharya Rule based Quadratic Equation, Quadratic Equation is one of the most favorite topics of SBI Clerk Pre 2021 Pre 2021. Questions on Quadratic Equations are asked in Quantitative Aptitude section. Generally, two quadratic equations in two different variables are given.

We have to solve both of the Quadratic equations to get to know the relation between both the variables.

Suppose we have two variables ‘x’ and ‘y’. The relationship between the variables can be any one of the following:

x > y

x < y

x = y or relation can’t be established between x & y

x ≥ y

x ≤ y

Meaning of different symbols, Before getting deep into the quadratic equations, lets try to understand the meaning of the basic operations used in finding the relationship between the variables –

(1) ‘>’ symbol: This symbol indicates that variable on the left side is definitely greater than the variable on the right side of the symbol.

(2) ‘<’ symbol: This symbol indicates that variable on the left is definitely smaller than the variable on the right side of the symbol.

For example: x<y means x is definitely smaller than y.

(3) ‘=’ symbol: This symbol indicates that variable on the left side is equal to the variable on the right side of the symbol.

(4) ‘≥’ symbol: This symbol indicates that variable on the left side is either greater than or equal to the variable on the right side of the symbol.

(5) ‘≤’ symbol: This symbol indicates that variable on the left side is either smaller than or equal to the variable on the right side of the symbol.

For example: x≤y means x is either smaller than y or equal to y.

General form of a Quadratic Equation

ax

Quadratic equation means that it will definitely have the maximum clerk pre 2021wer of the variable as ‘2’ which means we will always see ax

Or we can say that b can be 0, c can be 0 but a will never be 0.

While solving quadratic equation, you will always get 2 values of the equation. These 2 values are called roots of the equation. The roots of the equation always satisfy the equation. So in case of doubt, we can check the solution by putting the values back into the equation. If the equation turns out to be zero then our roots are correct.

Here are different kind of example of Quadratic Equation , so that we will get a very clear concept of the basic formation of a quadratic equation to get prepared for SBI Clerk Pre 2021 Pre.
