Homework Equations

\frac{4x^{2}-6x}{4x^{2}-9}

The Attempt at a Solution

the 4x² cancel each other out and 3 goes into 6 and 9
so the answer is
\frac{-2x}{-3}

but that seems to easy for the penultinate question on a higher GCSE paper.

You can't cancel out the 4x^2 like that! That's an illegal move.

You can only cancel out factors! never terms!
