expand (x-4)/((x+1)(x-2))

expand

\frac{x - 4}{( x + 1 ) ( x - 2 )}

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

Solution steps

\frac{x - 4}{( x + 1 ) ( x - 2 )}

Expand

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

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

\frac{( ( k + 1 ) ( 2 k + 3 ) ( 7 k + 8 ) )}{6}

\frac{( y - 2 ) ^{2}}{3}

\frac{4}{3 π ( x + 2 ) ^{3}}

\frac{( y - 2 ) ^{2}}{4}

(y^{2} - v y^{2}) (y d v + v d y)
