integral from 0 to 1-y of (6y)

\int_{0}^{1 - y} (6 y) d y

3 (- y + 1)^{2}

Solution steps

\int_{0}^{1 - y} 6 y d y

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 6 \cdot \int_{0}^{1 - y} y d y

Apply the Power Rule

= 6 [\frac{y ^{2}}{2}]_{0}^{1 - y}

Compute the boundaries:

\frac{1}{2} (- y + 1)^{2}

= 6 \cdot \frac{1}{2} (- y + 1)^{2}

Simplify

= 3 (- y + 1)^{2}
