simplify (x^2-8x-20)/(x^2-5x-50)

simplify

\frac{x ^{2} - 8 x - 20}{x ^{2} - 5 x - 50}

\frac{x + 2}{x + 5}

Solution steps

\frac{x ^{2} - 8 x - 20}{x ^{2} - 5 x - 50}

Factor

x^{2} - 8 x - 20 : (x + 2) (x - 10)

= \frac{( x + 2 ) ( x - 10 )}{x ^{2} - 5 x - 50}

Factor

x^{2} - 5 x - 50 : (x + 5) (x - 10)

= \frac{( x + 2 ) ( x - 10 )}{( x + 5 ) ( x - 10 )}

Cancel the common factor:

x - 10

= \frac{x + 2}{x + 5}

(1 + 4 i) (3 + 6 i)

7 \cdot 1 0^{- 5}

9 a - 3 a + 5 a

3 - 1

\frac{x ^{2} - 2 x - 48}{x ^{2} - 5 x - 24}
