integral from 6.1 to 7.2 of 12x^2-6x+4

\int_{6.1}^{7.2} 12 x^{2} - 6 x + 4 d x

545.578

Solution steps

\int_{6.1}^{7.2} 12 x^{2} - 6 x + 4 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_{6.1}^{7.2} 12 x^{2} d x - \int_{6.1}^{7.2} 6 x d x + \int_{6.1}^{7.2} 4 d x

\int_{6.1}^{7.2} 12 x^{2} d x = 585.068

\int_{6.1}^{7.2} 6 x d x = 43.89

\int_{6.1}^{7.2} 4 d x = 4.4

= 585.068 - 43.89 + 4.4

Simplify

= 545.578

\int_{0}^{1} 9 x^{2} + 144 d x

\int_{0}^{1} x \cdot 4 x^{3} d x

\int_{0}^{2} x^{8} d x

\int_{0}^{l n (2)} sinh (x) d x

\int_{3}^{4} \frac{10}{9 x ^{2}} d x
