integral from 0 to 3 of x^2+x^2-4x

\int_{0}^{3} x^{2} + x^{2} - 4 x d x

0

Solution steps

\int_{0}^{3} x^{2} + x^{2} - 4 x d x

Simplify

= \int_{0}^{3} 2 x^{2} - 4 x 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}^{3} 2 x^{2} d x - \int_{0}^{3} 4 x d x

\int_{0}^{3} 2 x^{2} d x = 18

\int_{0}^{3} 4 x d x = 18

= 18 - 18

Simplify

= 0

\int_{0}^{1} x π^{x} d x

\int_{0}^{l n (15)} tanh (x) d x

\int_{0}^{1} \frac{e ^{x}}{4 - e ^{2 x}} d x

\int_{- 1}^{3} (12 x^{3} - 2 x + 5) d x

\int_{0}^{4} x x^{2} + 1 d x
