simplify x/(sqrt(x)-4)

simplify

\frac{x}{x - 4}

\frac{x ( x + 4 )}{x - 16}

Solution steps

\frac{x}{x - 4}

Multiply by the conjugate

\frac{x + 4}{x + 4}

= \frac{x ( x + 4 )}{( x - 4 ) ( x + 4 )}

(x - 4) (x + 4) = x - 16

= \frac{x ( x + 4 )}{x - 16}

2 a + 4 (7 + 5 a)

4 m + 5 - 3 m

\frac{4 a ^{30}}{6 a ^{12}}

tanh^{2} (x) + sech^{2} (x)

- 5 (- 3 k - 2 m) + 8 m - 3 (2 m + 3 k)
