$\int_{0}^{3} | 2 x - 3 | d x$

Step 1

Split up the integral depending on where $2 x - 3$ is positive and negative.

$\int_{0}^{\frac{3}{2}} - 2 x + 3 d x + \int_{\frac{3}{2}}^{3} 2 x - 3 d x$

Step 2

Split the single integral into multiple integrals.

$\int_{0}^{\frac{3}{2}} - 2 x d x + \int_{0}^{\frac{3}{2}} 3 d x + \int_{\frac{3}{2}}^{3} 2 x - 3 d x$

Step 3

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

$- 2 \int_{0}^{\frac{3}{2}} x d x + \int_{0}^{\frac{3}{2}} 3 d x + \int_{\frac{3}{2}}^{3} 2 x - 3 d x$

Step 4
