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

x = -6,x=9

Step-by-step explanation:

multiply everything out then collect like terms

x = - 6, x = 9

Step-by-step 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

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
