Answer:
D x-1 x≠4
Step-by-step explanation:
x^2 +3x-4
-----------------
x+4
We know that x cannot equal 4 since the denominator would go to zero
Factor the numerator
(x+4) (x-1)
Cancel like terms (x+4)
x-1 x≠4
(x^2 + 3x - 4) / (x + 4).
Factor the numerator.
(x + 4) (x - 1) / (x + 4).
The terms (x + 4) cancel each other out.
The final answer is (x - 1); where x does not equal -4
