integral of (2x^2+3)^4x

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

\frac{1}{20} (2 x^{2} + 3)^{5} + C

Solution steps

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

Apply u-substitution

: \int \frac{u ^{4}}{4} d u

= \int \frac{u ^{4}}{4} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{4} \cdot \int u^{4} d u

Apply the Power Rule

: \frac{u ^{5}}{5}

= \frac{1}{4} \cdot \frac{u ^{5}}{5}

Substitute back

u = 2 x^{2} + 3

= \frac{1}{4} \cdot \frac{( 2 x ^{2} + 3 ) ^{5}}{5}

Simplify

\frac{1}{4} \cdot \frac{( 2 x ^{2} + 3 ) ^{5}}{5} : \frac{1}{20} (2 x^{2} + 3)^{5}

= \frac{1}{20} (2 x^{2} + 3)^{5}

Add a constant to the solution

= \frac{1}{20} (2 x^{2} + 3)^{5} + C

\int 3 x^{2} e^{x^{3 - 1}} d x

\int \frac{3 + 2 x}{x ^{2} - 9} d x

\int 2 x \cdot cos (2 x) d x

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

\int x^{2} y cos (x y) + 2 x sin (x y) d x
