Question

Find the roots of the quadratic equation y = x + x – 2 by factoring. A 1, -2 C 0,-2 B2, -1 D 1,-1 Find the roots of the quadratic equation

Answer 1

The given equation is

`y=x^2+x-2`

Then, we have to find two numbers which product is 2 and which difference is 1. Those numbers are 2 and -1.

`(x+2)(x-1)`

Hence, the roots are 1, -2. A is correct.
