Question

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

Answer 1

Answer:

$x = -15\\x = -5 \ \large \checkmark\\ x = -3\\x = 2\\x = 3 \ \large \checkmark \\x = 5$

Step-by-step explanation:

Note : the zero product property :

a × b = 0 ⇔ a = 0 or b = 0

=============================

(x + 5)(x – 3) = 0 ⇔ x + 5 = 0  or  x – 3 = 0

                           ⇔  x = –5      or  x = 3
