expand (2x-1)e^x

Solution

expand

(2 x - 1) e^{x}

Solution

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

Solution steps

(2 x - 1) e^{x}

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

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

Multiply:

1 \cdot e^{x} = e^{x}

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