Question

Perform the indicated operations. Simplify, and state the restrictions on the variable.
8/x+1 - 5/x+1

Answer 1

it's 3/x+1
the restriction is if x=-1

Answer 2

how do you find the restriction?

Answer 3

same denominator.. then you just have to subtract the numerator to get
3/(x+1)
but the denominator must not be equal to zero
so the restriction is when x+1=0
x=-1

Answer 4

okay thankyou!
