Asked by Jennifer
I used the U-substitution
x + 1 = u
u^2 -11u + 24
(u + 3)(u - 8)
( x + 1 + 3) ( x + 1 - 8)
(x + 4) ( X - 7 )
Is this correct?
x + 1 = u
u^2 -11u + 24
(u + 3)(u - 8)
( x + 1 + 3) ( x + 1 - 8)
(x + 4) ( X - 7 )
Is this correct?

There is an apparent mistake in your u-factoring.
u^2 -11u + 24
= (u - 3)(u - 8)
= (x-2)(x-7)
u^2 -11u + 24
= (u - 3)(u - 8)
= (x-2)(x-7)
