integral of 8(x+1)

Solution

\int 8 (x + 1) d x

Solution

8 (\frac{x ^{2}}{2} + x) + C

Solution steps

\int 8 (x + 1) d x

Take the constant out:

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

= 8 \cdot \int x + 1 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 8 (\int x d x + \int 1 d x)

\int x d x = \frac{x ^{2}}{2}

\int 1 d x = x

= 8 (\frac{x ^{2}}{2} + x)

Add a constant to the solution

= 8 (\frac{x ^{2}}{2} + x) + C
