Question

If (x + 1)(x - 3) = 5, then which of the following statements is true?
x + 1 = 0 or x - 3 = 0
x + 1 = 5 or x - 3 = 5
x - 4 = 0 or x + 2 = 0

Answer 1

None of the statements is true. Try testing each to confirm

Answer 2

x+1=5or x-3=5~~~~ should one of them be 1

Answer 3

(x + 1)(x - 3) = 5
x^2 -2x -3 =5
x^2 -2x -8 = 0
(x-4)(x+2)=0
(x-4)=0 or (x+2)=0

Answer 4

x - 4 = 0 or x + 2 = 0

Answer 5

this is true one

Answer 6

yeh its a good trip

Answer 9

@myko Sorry, but have you ever thought about typing the steps?

Answer 10

it's evident:
x - 4 = 0 or x + 2 = 0
is same as:
x=4 and x=-2
plug the values in the equation to check
