Question

What are the solutions to the equation (x + 2)(x - 7) = 0?

O x = 2 and x = -7
O x = 14 and x = -5
x = -2 and x = 7
O x= -14 and x = 5

Answer 1

x = -2 and x = 7

Explanation:

Since this is a multiplication, you can divide the equation into two parts to find what x values would make the equation equals to 0 because when you only need one multiple to equal 0 regardless of the value of the other multiple to make the equation equal to 0.

(x + 2) = 0 = > x = -2

(x - 7) = 0 = > x = 7
