The LCD is 6. Multiply the entire expression by 6, and then divide the result by 6:
6 [ <span>6(x^2-1) * 6x-1/6(x+1) ]
------------------------------------
6
When expanded and simplified, we get:
(36x^2 - 36)*6x - (x+1)
-------------------------------
6
or:
216x^3 - 216x - x - 1
----------------------------
6
Combining the two x-terms:
216x^3 - 217x -1
----------------------- (answer)
6</span>
First of all, you need to simplify the expressions in order to know whether they are equal. Then, it all depends on the expression, after you simplify an expression, it will seem much easier to determine that. <span />
