To solve this question, place each parenthesis equal to 0
(x + 1)(x - 5) = 0
(x + 1) = 0
(x - 5) = 0
Solve, place into each variable a solution to the problem.
x + 1 = 0
Isolate the x, subtract 1 from both sides
x + 1 (-1) = 0 (-1)
x = 0 - 1
x = -1
(x - 5) = 0
Isolate the x, add 5 to both sides
x - 5 = 0
x - 5 (+5) = 0 (+5)
x = 0 + 5
x = 5
you're answers are: x = -1, x = 5
Therefore, D) x = -1 or x = 5 is your answer
hope this helps
