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

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

\frac{212}{5}

Decimal

42.4

Solution steps

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

\int_{- 2}^{2} 3 x^{4} d x = \frac{192}{5}

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

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

= \frac{192}{5} - 0 + 4

Simplify

\frac{192}{5} - 0 + 4 : \frac{212}{5}

= \frac{212}{5}
