expand (9x^2-7x)e^x

Solution

expand

(9 x^{2} - 7 x) e^{x}

Solution

9 e^{x} x^{2} - 7 e^{x} x

Solution steps

(9 x^{2} - 7 x) e^{x}

= e^{x} (9 x^{2} - 7 x)

Apply the distributive law:

a (b - c) = ab - a c

a = e^{x}, b = 9 x^{2}, c = 7 x

= e^{x} \cdot 9 x^{2} - e^{x} \cdot 7 x

= 9 e^{x} x^{2} - 7 e^{x} x
