16-n^2 n^2-7n-30
_________ __________
n^2-5n-36 * n^2-n-12

  • Algebra -

    again, I think you mean:

    (16-n^2)/(n^2 - 5n - 36) * (n^2 - 7n - 30)/(n^2 - n - 12)

    = (4-n)(4+n)/( (n-9)(n+4)) * (n-10)(n+3)/( (n-4)(n+3) )
    = (n-10)/(n-9) , n ≠ ±4, -3

  • Algebra -

    Divide

    x^3y^2(x^2-3x-18)/xy^5(x^2-x-30)
