    So for the bottom it can't be 4 imp for you put 4 in there it will equal 0 for the top you can't but -5 in or else the top will be 0

    Your denominator can never be 0. \[\frac{ (-4)+5 }{ (4)^2+4(4) -32}=\frac{ 1 }{ 16+16-32 } = \frac{ 1 }{ 0 }\] \[\frac{ (-8)+5 }{ (-8)^2+4(-8)-32 } = \frac{ -3 }{ 64-32-32 } = \frac{ -3 }{ 0 }\]

    yea, your numerator can be 0 but not your denominator
