# Calculate: limit as x approaches 0 of 3/x+3/(x^2-x)

## Expression: $\lim _{x\to 0}(\frac{3}{x}+\frac{3}{x^{2}-x})$

Multiply by the conjugate of $\frac{3}{x}+\frac{3}{x^{2}-x}: \frac{\frac{9}{x^{2}}-\frac{9}{x^{4}-2x^{3}+x^{2}}}{\frac{3}{x}-\frac{3}{x^{2}-x}}$

$=\lim _{x\to 0}(\frac{\frac{9}{x^{2}}-\frac{9}{x^{4}-2x^{3}+x^{2}}}{\frac{3}{x}-\frac{3}{x^{2}-x}})$

Simplify $\frac{\frac{9}{x^{2}}-\frac{9}{x^{4}-2x^{3}+x^{2}}}{\frac{3}{x}-\frac{3}{x^{2}-x}}:{\quad}\frac{3}{x-1}$

$=\lim _{x\to 0}(\frac{3}{x-1})$

Plug in the value $x=0$

$=\frac{3}{0-1}$

Simplify

$=-3$
