# What is int 4 x^5 -7 x^4 + 9 x^3 -8 x^2 -3 x + 5 dx?

$\left(\frac{2}{3}\right) {x}^{6} - \left(\frac{7}{5}\right) {x}^{5} + \left(\frac{9}{4}\right) {x}^{4} - \left(\frac{8}{3}\right) {x}^{3} - \left(\frac{3}{2}\right) {x}^{2} + 5 x + C$
Use the power formula $\int {x}^{n}$ $\mathrm{dx}$=${x}^{n + 1} / \left(n + 1\right)$ for each term of the polynomial
