integral of 3x^2+2x^2

\int 3 x^{2} + 2 x^{2} d x

\frac{5 x ^{3}}{3} + C

Solution steps

\int 3 x^{2} + 2 x^{2} d x

Simplify

= \int 5 x^{2} d x

Take the constant out:

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

= 5 \cdot \int x^{2} d x

Apply the Power Rule

= 5 \cdot \frac{x ^{3}}{3}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{5 x ^{3}}{3}

Add a constant to the solution

= \frac{5 x ^{3}}{3} + C

\int \frac{x ^{2} + 4 x + 5}{x ^{2}} d x

\int sin^{3} (x) \cdot cos^{6} (x) d x

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

\int sin^{4} (x) - cos^{4} (x) d x

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