1. The problem statement, all variables and given/known data

Simplify fully the following equation

2. Relevant equations

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

3. The attempt at a solution

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

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!!
