Question

Which are solutions of the equation (x + 5)(x – 3) = 0? Check all that apply.

Answer 1

Hi there!

To find the solutions of the equation, just set them up equal to zero.

(x + 5)(x - 3) = 0

x + 5 = 0                    x - 3 = 0
    - 5    -5                     + 3    +3
--------------               ----------------
     x = -5                         x = 3


The solutions of your equation is x = -5 , x = 3.

Hope this helped! :)

Answer 2

X(to the second power) + 2x - 15 = 0
