\int 2x+8\mathrm{d}x
Evaluate the indefinite integral first.
\int 2x\mathrm{d}x+\int 8\mathrm{d}x
Integrate the sum term by term.
2\int x\mathrm{d}x+\int 8\mathrm{d}x
Factor out the constant in each of the terms.
x^{2}+\int 8\mathrm{d}x
Since \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} for k\neq -1, replace \int x\mathrm{d}x with \frac{x^{2}}{2}. 2 ni \frac{x^{2}}{2} marotabaga ko'paytirish.
x^{2}+8x
Find the integral of 8 using the table of common integrals rule \int a\mathrm{d}x=ax.
10^{2}+8\times 10-\left(0^{2}+8\times 0\right)
The definite integral is the antiderivative of the expression evaluated at the upper limit of integration minus the antiderivative evaluated at the lower limit of integration.
