    Solving Expression

    I need help solving this expression:

    ((x + 7) (x -4 )) / ((x - 7) (x - 4))

    these types of expressions confuse me.

    If you write the expression as

    \dfrac{(x+7)(x-4)}{(x-7)(x-4)}

    can you see what you may be able to get 'rid of' from the expression?

    Something similar from top and bottom?

    so these are eliminated giving you now \dfrac{(x+7)}{(x-7)}

    Do you see how that works?
