Step 1.1

Apply the distributive property.

$\int_{0}^{1} u (u - 3) + 2 (u - 3) d u$

Step 1.2

Step 1.3

Apply the distributive property.

$\int_{0}^{1} u \cdot u + u \cdot - 3 + 2 u + 2 \cdot - 3 d u$

Step 1.4

Reorder $u$ and $- 3$ .

$\int_{0}^{1} u \cdot u - 3 \cdot u + 2 u + 2 \cdot - 3 d u$

Step 1.5

Raise $u$ to the power of $1$ .

$\int_{0}^{1} u^{1} u - 3 u + 2 u + 2 \cdot - 3 d u$

Step 1.6

Raise $u$ to the power of $1$ .

$\int_{0}^{1} u^{1} u^{1} - 3 u + 2 u + 2 \cdot - 3 d u$

Step 1.7

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\int_{0}^{1} u^{1 + 1} - 3 u + 2 u + 2 \cdot - 3 d u$

Step 1.8

Add $1$ and $1$ .

$\int_{0}^{1} u^{2} - 3 u + 2 u + 2 \cdot - 3 d u$

$\int_{0}^{1} u^{2} - u - 6 d u$

Step 2

Split the single integral into multiple integrals.

$\int_{0}^{1} u^{2} d u + \int_{0}^{1} - u d u + \int_{0}^{1} - 6 d u$

Step 3

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

$\frac{1}{3} u^{3}]_{0}^{1} + \int_{0}^{1} - u d u + \int_{0}^{1} - 6 d u$

Step 4

Since $- 1$ is constant with respect to $u$ , move $- 1$ out of the integral.

$\frac{1}{3} u^{3}]_{0}^{1} - \int_{0}^{1} u d u + \int_{0}^{1} - 6 d u$

Step 5

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

$\frac{1}{3} u^{3}]_{0}^{1} - (\frac{1}{2} u^{2}]_{0}^{1}) + \int_{0}^{1} - 6 d u$

Step 6

Combine $\frac{1}{2}$ and $u^{2}$ .

$\frac{1}{3} u^{3}]_{0}^{1} - (\frac{u^{2}}{2}]_{0}^{1}) + \int_{0}^{1} - 6 d u$

Step 7

Apply the constant rule.

$\frac{1}{3} u^{3}]_{0}^{1} - (\frac{u^{2}}{2}]_{0}^{1}) + - 6 u]_{0}^{1}$
