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

expand

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

\frac{x ^{2} - 2 x + 1}{x ^{2} + 3 x + 2}

Solution steps

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

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

= \frac{x ^{2} - 2 x + 1}{( x + 1 ) ( x + 2 )}

Expand

(x + 1) (x + 2) : x^{2} + 3 x + 2

= \frac{x ^{2} - 2 x + 1}{x ^{2} + 3 x + 2}

\frac{( n ( n + 1 ) ( n + 2 ) )}{6}

(e^{3 x} + 1)^{2}

\frac{2 x ^{2} + 5 x + 7}{( x + 1 ) ( x ^{2} + x + 1 )}

\frac{s ^{2} + 2 - e ^{- s}}{s ( s ^{2} + 16 )}

A (2, - 3) e B (- 2, 1)
