    no it's -4 i've been working on it, but it's no factoring :/

    Because factoring x²+4x-4 is pretty difficult.

    Well, It's safe to say that it cannot be factored.

    Using the quadratic formula would be the easiest method

    \[\lim_{x \rightarrow -3} \frac{ x^2+4x-4 }{ x-3 }\]

    You could try factoring out the x. x(x+4)-4

    I don't see why you have to factor the numerator. All you have to do is plug -3 into x.

    What do you mean? Ave to do is plug -3, like this:\[\frac{ (-3)^2 + 4(-3) - 4 }{ (-3) - 3 }\]
