If (x + 1) (x-3) = 5, then which of the following statements is true?

x+1=5 or X-3 = 5

x-4 = 0 or x + 2 = 0

x + 1 = 0 or X-3 = 0

x=-2 or x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x2-2x-3=5

Step 2: Subtract 5 from both sides.

x2-2x-3-5=5-5

x2-2x-8=0

Step 3: Factor left side of equation.

(x+2) (x-4) = 0

Step 4: Set factors equal to 0.

x+2=0 or x-4=0

x=-2 or x=4
