How do you simplify #(x^2 - 1) /(x^2 - 3x - 10)(x^2 + 5x + 6)/ (x^2 - 3x – 4)(x^2 - x - 20)/(x^2 + 2x – 3)#?

#((x - 1)(x + 1))/((x + 2)(x - 5)) . ((x + 2)(x + 3))/((x + 1)(x - 4)). ((x + 4)(x - 5))/((x - 1)(x + 3))# =

= #(x + 4)/(x - 4)#

How do you simplify #(x^2 - 1) /(x^2 - 3x - 10)*(x^2 + 5x + 6)/ (x^2 - 3x – 4)*(x^2 - x - 20)/(x^2 + 2x – 3)#?
