What is 3x-12 divided by x^2-5x Then TIMES this by 7x/4-x.... Thank You!

3x-12 x 7x

x

^{2}-5x 4-x(3x-12)*(7x) ------> ____(3x)(7x) - (12)(7x)

(x

^{2}-5x)*(4-x) (x^{2})(4) + (x^{2})(-x) - (5x)(4) - (5x)(-x) ------> __21x

^{2}- 84x 4x

^{2}- x^{3}- 20x + 5x^{2}you're gonna want to clean this up a bit :)

Final Answer ------> __21x (x - 4)

-x

^{3}+ 9x^{2}- 20x
