integral of 90x

Solution

\int 90 x d x

Solution

45 x^{2} + C

Solution steps

\int 90 x d x

Take the constant out:

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

= 90 \cdot \int x d x

Apply the Power Rule

: \frac{x ^{2}}{2}

= 90 \cdot \frac{x ^{2}}{2}

Simplify

90 \cdot \frac{x ^{2}}{2} : 45 x^{2}

= 45 x^{2}

Add a constant to the solution

= 45 x^{2} + C
