$2 x^{2} - 5 x$

Step 1

Split the single integral into multiple integrals.

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

Step 2

Since $2$ is constant with respect to $x$ , move $2$ out of the integral.

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

Step 3

By the Power Rule, the integral of $x^{2}$ with respect to $x$ is $\frac{1}{3} x^{3}$ .

$2 (\frac{1}{3} x^{3} + C) + \int - 5 x d x$

Step 4

Since $- 5$ is constant with respect to $x$ , move $- 5$ out of the integral.

$2 (\frac{1}{3} x^{3} + C) - 5 \int x d x$

Step 5

By the Power Rule, the integral of $x$ with respect to $x$ is $\frac{1}{2} x^{2}$ .

$2 (\frac{1}{3} x^{3} + C) - 5 (\frac{1}{2} x^{2} + C)$

Step 6.2.1

Combine $2$ and $\frac{1}{3}$ .

$\frac{2}{3} x^{3} - 5 (\frac{1}{2}) x^{2} + C$

Step 6.2.2

Combine $- 5$ and $\frac{1}{2}$ .

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

Step 6.2.3

Move the negative in front of the fraction.

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