Question 5b) please, what have i done wrong?

2(x+3)(x+4)/(x+1)(x-5) x (x+1)/4(x+3)

At the denominator you have

(x-5)×4=4x-20.

But:

2(x+4)/(4(x-5))=(x+4)/2/(x-5)

see explanation

Step-by-step explanation:

Given

×

Cancel the common factors (x + 1), (x+3) on the numerator/ denominator

and cancel 2 and 4 on the numerator/ denominator by 2

=

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?
