expand (xe^x-e^x)*2x-1

expand

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

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

Solution steps

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

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

Expand

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

= 2 e^{x} x^{2} - 2 e^{x} x - 1

\frac{4 ( 341 - 11 )}{11}

\frac{4 x ^{2} + 8 x + 2}{( x + 1 ) ^{2}}

2 x + 3 (x - 2 = x + 22)

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

(4 d - 3 e) (2 d + e)
