Question

Find the roots of (x+2)(x-7)=0

Answer 1

x = -2 or x = 7

Explanation:

x - 7 = 0 or x + 2 = 0

x = 7 or x = - 2

Answer 2

the roots are x = -2, +7

Explanation:

The roots are the values of x that make one of the factors be zero. Whenever a factor is zero, the product is zero.

To make x+2 = 0, x = -2.

To make x-7 = 0, x = 7.
