Multiply the equation by x/x which will leave you with [x(x+1)]/[x(1/x+1)]
Distribute the x in the denominator and you are left with [x(x+1)]/[1+x]
You can now cancel the (x+1) to be left with just x. The Limit as x -> -1 of x is just -1.

Do you mean (x+1) / (1/(x+1))?

If you have been taught L'Hospital's Rule, that is the one to use. The differentiation is easy.

If you don't know L'Hospital's Rule, the solution given by the poster above me works fine.

(x+1) / (1/(x+1) =
(x+1)^2
lim (x+1)^2 = 0
x→0

lim f(x) / g(x) = lim f'(x) / lim g'(x)
lim f'(x) = 1
lim g'(x) = - 1 / x^2

when we solve, we get -1
