expand (x^2+3x+1)/((x+2)(x-1))

expand

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

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

Solution steps

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

Expand

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

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

(e^{x} - 1) (e^{x} - 2)

\frac{( ( n + k ) ( n + k ) ! )}{k ! n !}

9 (x + δ x)^{3}

10 (x + 2 (e^{- 0.5 x} - 1)) - 0.2 x^{2}

\frac{x}{( 3 x ^{2} - 4 ) ^{4}}
