Please help with this calculus problem?

First step is to just substitute the value for x and see what happens. That works for the second problem, since you get a finite number, so you're done.
For the first problem, substitution yields 0/0, so that doesn't work. In that case, factor the numerator and denominator and cancel out common factors.
For the third problem, substitution doesn't work, since x is approaching infinity. In that case, in each polynomial (numerator and denominator), only the term with the highest exponent is significant, so you're left with (x^2)/(x^2) which becomes 1.
