integral from-1 to 5 of 3x^2+8x

Solution

\int_{- 1}^{5} 3 x^{2} + 8 x d x

Solution

222

Solution steps

\int_{- 1}^{5} 3 x^{2} + 8 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_{- 1}^{5} 3 x^{2} d x + \int_{- 1}^{5} 8 x d x

\int_{- 1}^{5} 3 x^{2} d x = 126

\int_{- 1}^{5} 8 x d x = 96

= 126 + 96

Simplify

= 222
