expand 3x^2e^{3x}+2x(e^{3x}-4)

expand

3 x^{2} e^{3 x} + 2 x (e^{3 x} - 4)

3 x^{2} e^{3 x} + 2 e^{3 x} x - 8 x

Solution steps

3 x^{2} e^{3 x} + 2 x (e^{3 x} - 4)

= 3 e^{3 x} x^{2} + 2 x (e^{3 x} - 4)

Expand

2 x (e^{3 x} - 4) : 2 e^{3 x} x - 8 x

= 3 x^{2} e^{3 x} + 2 e^{3 x} x - 8 x

- \frac{e ^{- λ t} ( 1 - e ^{- λ t} )}{λ}

\frac{z ^{2} + i}{( z ^{3} - i ) ^{2}}
