integral of-2x

Solution

integral

- 2 x

Solution

- x^{2} + C

Solution steps

\int - 2 x d x

Take the constant out:

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

= - 2 \cdot \int x d x

Apply the Power Rule

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

Simplify

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

= - x^{2}

Add a constant to the solution

= - x^{2} + C
