Question

Integrate with respect to x :
∫20x2+1dx

Answer 1

Answer on Question #50942 – Math – Integral Calculus

Integrate with respect to $x$:

$$\int 20x^2 + 1\,dx$$

Solution

$$\int 20x^2 + 1\,dx = 20\int x^2 + 1\,dx = 20\int x^2\,dx + \int dx = \frac{20}{3}x^3 + x + C,$$

where $C$ is an arbitrary real constant.
