integral from 0 to 1 of 1-2x-3x^2

Solution

\int_{0}^{1} 1 - 2 x - 3 x^{2} d x

Solution

- 1

Solution steps

\int_{0}^{1} 1 - 2 x - 3 x^{2} 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

= \int_{0}^{1} 1 d x - \int_{0}^{1} 2 x d x - \int_{0}^{1} 3 x^{2} d x

\int_{0}^{1} 1 d x = 1

\int_{0}^{1} 2 x d x = 1

\int_{0}^{1} 3 x^{2} d x = 1

= 1 - 1 - 1

Simplify

= - 1
