limit as x approaches-1 of (x^3-x)/(x+1)

x \to - 1 lim (\frac{x ^{3} - x}{x + 1})

2

Solution steps

x \to - 1 lim (\frac{x ^{3} - x}{x + 1})

Simplify

\frac{x ^{3} - x}{x + 1} : x (x - 1)

= x \to - 1 lim (x (x - 1))

Plug in the value

x = - 1

= (- 1) (- 1 - 1)

Simplify

= 2

x \to 2 lim (5 x + 9)

x \to π lim (sin (\frac{x}{2} - π))

p \to 2 lim (p^{2} + p + 5)

x \to \infty lim ((- 5)^{n})

x \to 2 lim (\frac{2 - x}{x ^{3} - 8})
