integral of x^2+10x-90

\int x^{2} + 10 x - 90 d x

\frac{x ^{3}}{3} + 5 x^{2} - 90 x + C

Solution steps

\int x^{2} + 10 x - 90 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 x^{2} d x + \int 10 x d x - \int 90 d x

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

\int 10 x d x = 5 x^{2}

\int 90 d x = 90 x

= \frac{x ^{3}}{3} + 5 x^{2} - 90 x

Add a constant to the solution

= \frac{x ^{3}}{3} + 5 x^{2} - 90 x + C

\int x^{2} e^{- 4 x^{3}} d x

\int \frac{t}{t ^{2} + 1} d t

\int \frac{z ^{5}}{3 9 + z ^{6}} d z

\int 4 x^{\frac{1}{3}} + 10 x^{- \frac{1}{3}} d x

\int - 15 x^{4} (- 3 x^{5} - 1) d x
