simplify (sqrt(-x^2-4x+5))/(sqrt(-x^2-2x-8))

simplify

\frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8}

\frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8}

Solution steps

\frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8}

Apply radical rule:

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

\frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8} = \frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8}

= \frac{- x ^{2} - 4 x + 5}{- x ^{2} - 2 x - 8}
