Post a New Question

I didn't help with my last math problem:
Perform the indicated operations.

14x-7/x^2+3x-4 * x^2+6x+8/2x^2+5x-3 / x^2+2x/x^2+2x-3

I appreciate the help.

    I will assume you meant the following:

    (14x-7)/(x^2+3x-4) * (x^2+6x+8)/(2x^2+5x-3) รท (x^2+2x)/(x^2+2x-3)

    Then everything factors very nicely and my answer was 7/x

    Don't forget the restrictions of
    x not= -4,1,-3,1/2,-2,0

    Hint:(my restrictions should give you a clue what the factors of the denominators were)
