Question

Simplify x^2-36/x^2-12x+36
A. x-6/x-3
B. x+6/x-6
C. x-3/x+3
D. x+3/x+6

Answer 1

The numerator is a difference of two square: (a^2-b^2)=(a+b)(a-b)
For the denomiantor, you must factor it as well, find two numbers that multiply to be 36 and add up to be -12.

Once the numerator and denomiator have been factored, you will see that a term will divide out, leaving you with your answer
