Evaluate the Integral

$\int 3 - 3 x d x$

Step 1

Split the single integral into multiple integrals.

$\int 3 d x + \int - 3 x d x$

Step 2

Apply the constant rule.

$3 x + C + \int - 3 x d x$

Step 3

Since $- 3$ is constant with respect to $x$ , move $- 3$ out of the integral.

$3 x + C - 3 \int x d x$

Step 4

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

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

Step 5.2.1

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

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

Step 5.2.2

Move the negative in front of the fraction.

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