Which expression is equal to 2x^2+2x−40/4x^2−12x−16 ⋅ 3x^2−3/x^2−5x

3(x+1)/2x

3(x−1)/2x

3(x−1)(x+5)/2x(x−5)

3(x−1)(x+4)/2x(x−4)

  3(x−1)(x+5)/(2x(x−5))

Step-by-step explanation:

In general simplifying something like this requires you factor the various polynomials to see what factors may cancel.
