Quadratic Equation For CMAT

Hi buddy as I am going to appear in CMAT exam and looking for Quadratic Equation sample question paper for its preparation , so would you plz provide me same here ??

As you asking here I am providing sample question of Quadratic Equation for CMAT exam preparation :

Solving Quadratic Equations: Examples

Solve (x + 1)(x – 3) = 0.

This is a quadratic, and I'm supposed to solve it. I could multiply the left-hand side, simplify to find the coefficients, plug them into the Quadratic Formula, and chug away to the answer.

But why would I? I mean, for heaven's sake, this is factorable, and they've already factored it and set it equal to zero for me. While the Quadratic Formula would give me the correct answer, why bother with it? Instead, I'll just solve the factors:

(x + 1)(x – 3) = 0
x + 1 = 0 or x – 3 = 0
x = –1 or x = 3

The solution is x = –1, 3

Solve x2 + x – 4 = 0.

This one doesn't factor (since there are no factors of (1)(–4) = –4 that add to +1), and this isn't formatted as "(squared part) equals (a number)", so I can't use square-rooting to solve. This leaves me with completing the square (yuck!) or the Quadratic Formula. I'll use the Formula:

x = [-1
