$\int 4 x - 5 d x$

Step 1

Split the single integral into multiple integrals.

$\int 4 x d x + \int - 5 d x$

Step 2

Since $4$ is constant with respect to $x$ , move $4$ out of the integral.

$4 \int x d x + \int - 5 d x$

Step 3

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

$4 (\frac{1}{2} x^{2} + C) + \int - 5 d x$

Step 4

Apply the constant rule.

$4 (\frac{1}{2} x^{2} + C) - 5 x + C$

Step 5
