expand ((x-5)(x^2+5x+4))/(x^2-2x-8)

expand

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

\frac{x ^{3} - 21 x - 20}{x ^{2} - 2 x - 8}

Solution steps

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

Expand

(x - 5) (x^{2} + 5 x + 4) : x^{3} - 21 x - 20

= \frac{x ^{3} - 21 x - 20}{x ^{2} - 2 x - 8}
