expand (1-2x)*e^x

Solution

expand

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

Solution

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

Solution steps

(1 - 2 x) e^{x}

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

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

Multiply:

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

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