Simplify Fraction

  1. Apr 11, 2007 #1
    1. The problem statement, all variables and given/known data

    Simplify fully the following equation

    2. Relevant equations

    [tex]\frac{4x^{2}-6x}{4x^{2}-9}[/tex]


    3. The attempt at a solution

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

    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!!
