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

Solution

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

Solution

\frac{26}{3}

+1

Decimal

8.66666 \dots

Solution steps

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

\int_{- 1}^{1} 4 x^{2} d x = \frac{8}{3}

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

= \frac{8}{3} + 6

Simplify

\frac{8}{3} + 6 : \frac{26}{3}

= \frac{26}{3}
