Simplify ( square root of 3)/(-1- square root of 5)

$\frac{\sqrt{3}}{- 1 - \sqrt{5}}$

Multiply $\frac{\sqrt{3}}{- 1 - \sqrt{5}}$ by $\frac{- 1 + \sqrt{5}}{- 1 + \sqrt{5}}$ .

$\frac{\sqrt{3}}{- 1 - \sqrt{5}} \cdot \frac{- 1 + \sqrt{5}}{- 1 + \sqrt{5}}$

Simplify terms.

Multiply $\frac{\sqrt{3}}{- 1 - \sqrt{5}}$ by $\frac{- 1 + \sqrt{5}}{- 1 + \sqrt{5}}$ .

$\frac{\sqrt{3} (- 1 + \sqrt{5})}{(- 1 - \sqrt{5}) (- 1 + \sqrt{5})}$

Expand the denominator using the FOIL method.

$\frac{\sqrt{3} (- 1 + \sqrt{5})}{1 - \sqrt{5} + \sqrt{5} - {\sqrt{5}}^{2}}$

Simplify.

$\frac{\sqrt{3} (- 1 + \sqrt{5})}{- 4}$

Apply the distributive property.

$\frac{\sqrt{3} \cdot - 1 + \sqrt{3} \sqrt{5}}{- 4}$

Move $- 1$ to the left of $\sqrt{3}$ .

$\frac{- 1 \cdot \sqrt{3} + \sqrt{3} \sqrt{5}}{- 4}$

Combine using the product rule for radicals.

$\frac{- 1 \cdot \sqrt{3} + \sqrt{3 \cdot 5}}{- 4}$

Simplify each term.

Rewrite $- 1 \sqrt{3}$ as $- \sqrt{3}$ .

$\frac{- \sqrt{3} + \sqrt{3 \cdot 5}}{- 4}$

Multiply $3$ by $5$ .

$\frac{- \sqrt{3} + \sqrt{15}}{- 4}$

Simplify with factoring out.

Move the negative in front of the fraction.

$- \frac{- \sqrt{3} + \sqrt{15}}{4}$

Factor $- 1$ out of $- \sqrt{3}$ .

$- \frac{- (\sqrt{3}) + \sqrt{15}}{4}$

Factor $- 1$ out of $\sqrt{15}$ .

$- \frac{- (\sqrt{3}) - 1 (- \sqrt{15})}{4}$

Factor $- 1$ out of $- (\sqrt{3}) - 1 (- \sqrt{15})$ .

$- \frac{- (\sqrt{3} - \sqrt{15})}{4}$

Simplify the expression.

Rewrite $- (\sqrt{3} - \sqrt{15})$ as $- 1 (\sqrt{3} - \sqrt{15})$ .
