Answer to Problem 18CLR

The simplified expression is 3x(x−3)2(3x−9) .

Explanation of Solution

Given information:

The expression is 18x2x2−2x−8·x2−x−612x÷3x−9x−4 .

Calculation: to find the simplified expression, first factor and then simplify,

18x2x2−2x−8·x2−x−612x÷3x−9x−4=18x2(x−4)(x+2)·(x−3)(x+2)12x·x−43x−9    [factorise and simplify]18x2x2−2x−8·x2−x−612x÷3x−9x−4=3x(x−3)2(3x−9)                                             [divide out common factor]

Thus, the simplified expression is 3x(x−3)2(3x−9) .
