Eric Garner · Answer 2

x² - 3x - 10 = 0

Step-by-step explanation:

Given there are 2 solutions then the equation is a quadratic.

Since the solutions are x = - 2 and x = 5 then

the factors are (x + 2) and (x - 5) and

f (x) = (x + 2) (x - 5) ← expand factors

= x² - 3x - 10, hence the equation is

x² - 3x - 10 = 0
