integral of 4x^2+5x-2

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

\frac{4 x ^{3}}{3} + \frac{5 x ^{2}}{2} - 2 x + C

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 4 x^{2} d x + \int 5 x d x - \int 2 d x

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

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

\int 2 d x = 2 x

= \frac{4 x ^{3}}{3} + \frac{5 x ^{2}}{2} - 2 x

Add a constant to the solution

= \frac{4 x ^{3}}{3} + \frac{5 x ^{2}}{2} - 2 x + C

\int (\frac{π}{x ^{4}} + e^{2} x) d x

\int x cosh (a x) d x

\int 4 e^{(y - 4) x}

\int \frac{a}{2 x} d x

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