Limits: lim x-> 0 (x+3x2)/4x, lim x->2 (x^-4x+4)/(x^3-4x)

[sail0r]

Two short limits questions here. I am just not seeing where to go with them.

lim x-> 0 (x+3x[sup:1vp0im9d]2[/sup:1vp0im9d])/4x

&

lim x->2 (x[sup:1vp0im9d]2[/sup:1vp0im9d]-4x+4)/(x[sup:1vp0im9d]3[/sup:1vp0im9d]-4x)

Re: Limits!

Do a little factoring and simplify. They are easy if you do that.

Re: Limits!

Factor an x out of the denominator. It is not a difference of cubes. 4x is not a cube. The numerator is a perfect square.
