Question

, what are the solutions to (x+1)(x-4)=50? Select ALL that apply. *

Answer 1

x = - 6, x = 9

Explanation:

Given

(x + 1)(x - 4) = 50 ← expand parenthesis using FOIL

x² - 3x - 4 = 50 ( subtract 50 from both sides )

x² - 3x - 54 = 0 ← in standard form

(x + 6)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 9 = 0 ⇒ x = 9

Answer 2

x = -6,x=9

Explanation:

multiply everything out then collect like terms
