expand (e^xx-e^x)(2x-1)

Solution

expand

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

Solution

2 e^{x} x^{2} - 3 e^{x} x + e^{x}

Solution steps

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

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = e^{x} x, b = - e^{x}, c = 2 x, d = - 1

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

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= 2 e^{x} xx - 1 \cdot e^{x} x - 2 e^{x} x + 1 \cdot e^{x}

Simplify

2 e^{x} xx - 1 \cdot e^{x} x - 2 e^{x} x + 1 \cdot e^{x} : 2 e^{x} x^{2} - 3 e^{x} x + e^{x}

= 2 e^{x} x^{2} - 3 e^{x} x + e^{x}
