simplify (sqrt(4-x^2))/(sqrt(x^2-1))

simplify

\frac{4 - x ^{2}}{x ^{2} - 1}

\frac{- x ^{2} + 4}{x ^{2} - 1}

Solution steps

\frac{4 - x ^{2}}{x ^{2} - 1}

Apply radical rule:

\frac{a}{b} = \frac{a}{b}

\frac{4 - x ^{2}}{x ^{2} - 1} = \frac{4 - x ^{2}}{x ^{2} - 1}

= \frac{4 - x ^{2}}{x ^{2} - 1}

(9.8 \cdot 1 0^{3}) (2.4 \cdot 1 0^{7})

- x^{2} (x + 1)^{2}

3 e^{- 6}
