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

expand

(2 x + 1) l e f t (1 + x - x^{2})

- 2 e l x^{3} f t + e l x^{2} f t + 3 e l x f t + e l f t

Solution steps

(2 x + 1) l e f t (1 + x - x^{2})

= e l f t (2 x + 1) (1 + x - x^{2})

Expand

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

= l e f t (- 2 x^{3} + x^{2} + 3 x + 1)

Expand

l e f t (- 2 x^{3} + x^{2} + 3 x + 1) : - 2 e l x^{3} f t + e l x^{2} f t + 3 e l x f t + e l f t

= - 2 e l x^{3} f t + e l x^{2} f t + 3 e l x f t + e l f t

\frac{( x + 1 ) ^{2} ( 4 x ^{4} + 13 x ^{3} + 6 x ^{2} - x - 4 )}{( x + 2 ) ^{3}}

\frac{z \cdot ( 3 \cdot z - 1 )}{( z + 1 ) \cdot ( z + 2 )}

\frac{0.002412 ( z + 2.51 )}{z}

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

\frac{\partial}{\partial y} ((z) (8 x yz - e^{z}))
