expand e^x(x^2-cos(x))

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

a = e^{x}, b = x^{2}, c = cos (x)

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

\frac{( e + 1 ) ( e - 1 )}{2}

e^{3 t} u (t + 3)

\frac{k - 1}{( n + 1 - k ) ^{2}}

\frac{( 2 x + 1 ) ^{4}}{8}

\frac{10}{x ( x - 5 )}
