integral of (3x-2)^2x

\int (3 x - 2)^{2} x d x

\frac{9}{2} x^{4} - \frac{9 x ^{4}}{4} - 4 x^{3} + 2 x^{2} + C

Solution steps

\int (3 x - 2)^{2} x d x

Apply Integration By Parts

: \frac{1}{2} x^{2} (3 x - 2)^{2} - \int 3 x^{2} (3 x - 2) d x

= \frac{1}{2} x^{2} (3 x - 2)^{2} - \int 3 x^{2} (3 x - 2) d x

\int 3 x^{2} (3 x - 2) d x = \frac{9 x ^{4}}{4} - 2 x^{3}

= \frac{1}{2} x^{2} (3 x - 2)^{2} - (\frac{9 x ^{4}}{4} - 2 x^{3})

Simplify

\frac{1}{2} x^{2} (3 x - 2)^{2} - (\frac{9 x ^{4}}{4} - 2 x^{3}) : \frac{9}{2} x^{4} - \frac{9 x ^{4}}{4} - 4 x^{3} + 2 x^{2}

= \frac{9}{2} x^{4} - \frac{9 x ^{4}}{4} - 4 x^{3} + 2 x^{2}

Add a constant to the solution

= \frac{9}{2} x^{4} - \frac{9 x ^{4}}{4} - 4 x^{3} + 2 x^{2} + C

\int 4 x^{2} cos (x) d x

\int \frac{25 - ( x - 3 ) ^{2}}{x - 3} d x

\int 3 (x - 2)^{4} d x

\int 6 x^{2} - 4 x + 2 d x

\int \frac{x ^{2} + x}{x ^{2} - 1} d x
