Question

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

Answer 1

Explanation:

if ab=0,then either a=0 or b=0 or both are zero.

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

either x+5=0,x=-5

or x-3=0,x=3

so solutions are -5,3

Answer 2

x = 3, -5

Explanation:

To approach this problem, I would break it into two parts and set them equal to 0 and solve for x.

So it would look like this:

`x + 5 = 0\\x = -5\\\\x - 3 = 0\\x = 3`
