Answer:

x = - [tex]\frac{2}{5}[/tex], x = 5

Step-by-step explanation:

Given

f(x) = (x - 5)(5x + 2)

To obtain the solutions set f(x) = 0, that is

(x - 5)(5x + 2) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5 ← larger x

5x + 2 = 0 ⇒ 5x = - 2 ⇒ x = - [tex]\frac{2}{5}[/tex] ← smaller x
