$\int_{0}^{2} (\frac{4}{5} t^{3} - \frac{3}{4} t^{2} + \frac{2}{5} t) d t$

Step 1

Remove parentheses.

$\int_{0}^{2} \frac{4}{5} t^{3} - \frac{3}{4} t^{2} + \frac{2}{5} t d t$

Step 2

Split the single integral into multiple integrals.

$\int_{0}^{2} \frac{4}{5} t^{3} d t + \int_{0}^{2} - \frac{3}{4} t^{2} d t + \int_{0}^{2} \frac{2}{5} t d t$

Step 3

Since $\frac{4}{5}$ is constant with respect to $t$ , move $\frac{4}{5}$ out of the integral.

$\frac{4}{5} \int_{0}^{2} t^{3} d t + \int_{0}^{2} - \frac{3}{4} t^{2} d t + \int_{0}^{2} \frac{2}{5} t d t$

Step 4

By the Power Rule, the integral of $t^{3}$ with respect to $t$ is $\frac{1}{4} t^{4}$ .

$\frac{4}{5} \frac{1}{4} t^{4}]_{0}^{2} + \int_{0}^{2} - \frac{3}{4} t^{2} d t + \int_{0}^{2} \frac{2}{5} t d t$

Step 5

Since $- \frac{3}{4}$ is constant with respect to $t$ , move $- \frac{3}{4}$ out of the integral.

$\frac{4}{5} \frac{1}{4} t^{4}]_{0}^{2} - \frac{3}{4} \int_{0}^{2} t^{2} d t + \int_{0}^{2} \frac{2}{5} t d t$

Step 6

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

$\frac{4}{5} \frac{1}{4} t^{4}]_{0}^{2} - \frac{3}{4} \frac{1}{3} t^{3}]_{0}^{2} + \int_{0}^{2} \frac{2}{5} t d t$

Step 7

Since $\frac{2}{5}$ is constant with respect to $t$ , move $\frac{2}{5}$ out of the integral.

$\frac{4}{5} \frac{1}{4} t^{4}]_{0}^{2} - \frac{3}{4} \frac{1}{3} t^{3}]_{0}^{2} + \frac{2}{5} \int_{0}^{2} t d t$

Step 8

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

$\frac{4}{5} \frac{1}{4} t^{4}]_{0}^{2} - \frac{3}{4} \frac{1}{3} t^{3}]_{0}^{2} + \frac{2}{5} \frac{1}{2} t^{2}]_{0}^{2}$
