integral of x^2-7x+8

Solution

\int x^{2} - 7 x + 8 d x

Solution

\frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 8 x + C

Solution steps

\int x^{2} - 7 x + 8 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 7 x d x + \int 8 d x

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

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 8 d x = 8 x

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 8 x

Add a constant to the solution

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 8 x + C
