expand x^2(x+3)e^x

Solution

expand

x^{2} (x + 3) e^{x}

Solution

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

Solution steps

x^{2} (x + 3) e^{x}

= e^{x} x^{2} (x + 3)

Apply the distributive law:

a (b + c) = ab + a c

a = x^{2} e^{x}, b = x, c = 3

= x^{2} e^{x} x + x^{2} e^{x} \cdot 3

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

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

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