(6x^3 - 6x^2) / (x^4 + 5x^3) Multiplied by (2x^2 + 2x - 40) / (3x^2 - 15x + 12)

when you simplify it down enough you get 4/x
bring out common factors first, so in the top of the first one you would have 6x^2(x-1) and in the top on the right you would have 2(x^2+x-20)
this will make the factoring and simplifying job much easier
once you factor out all the common terms, then factor the other quadratics, cross out like terms and you should end up with 12x^2/3x^3
which simplifies to 4/x

at the same time as there's a marvelous decision outdoors parentheses, multiply each and each of the words interior by technique of that huge style. Then combine any like words (having the very similar variable). -20x + 15 (-3x - 4x) + (5 - 2) = -7x + 3 2x + (5 + 7) = 2x + 12 30 x a million/3m = 10m 30 x -3/5 n = -18n -20 x 3/4 m = -15m -20 x 2/5 n = -8n (10m - 15n) + (-18n - 8n) = -5m - 26n desire that permits clarify it

Factor and cancel out like terms in top and bottom.
Answer is: (6x(2x-8))/((x^3(3x-12)))

6x^3-6x^2/ x^4+5x^3 * 2x^2+2x-40/ 3x^2-15x+12
x/x^3(x+5) * (2x-8)(x+5)/(3x-3)(x-4)
x 2(x-4)(x+5)
------- * --------------------------
x^3(x+5) (3x-3)(x-4)
2/x^2(3x-3)=2/6x^3-6x^2=2/x--answer
