+129852 (18x^2) /( 55x) * (121x^3) / (9x^4) .....notice that we can rearrange this as....
(18/9)* ( 121/55) * (x^2 * x^3) / (x * x^4) =
2 * [ ( 11*11) / (5*11) ] *[ (x^5)/(x^5)] ...notice that the last terms "cancel" and we're left with...
2 * (11*11)/(5*11) and each "11" in both numerator and denominator "cancels"....so we have...
2 * (11/5) = 22/5
