integral from 1 to 3 of 3x^2+4x+3

Solution

\int_{1}^{3} 3 x^{2} + 4 x + 3 d x

Solution

48

Solution steps

\int_{1}^{3} 3 x^{2} + 4 x + 3 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}^{3} 3 x^{2} d x + \int_{1}^{3} 4 x d x + \int_{1}^{3} 3 d x

\int_{1}^{3} 3 x^{2} d x = 26

\int_{1}^{3} 4 x d x = 16

\int_{1}^{3} 3 d x = 6

= 26 + 16 + 6

Simplify

= 48
