\int 2x^{2}-3x-2\mathrm{d}x
Evaluate the indefinite integral first.
\int 2x^{2}\mathrm{d}x+\int -3x\mathrm{d}x+\int -2\mathrm{d}x
Integrate the sum term by term.
2\int x^{2}\mathrm{d}x-3\int x\mathrm{d}x+\int -2\mathrm{d}x
Factor out the constant in each of the terms.
\frac{2x^{3}}{3}-3\int x\mathrm{d}x+\int -2\mathrm{d}x
Since \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} for k\neq -1, replace \int x^{2}\mathrm{d}x with \frac{x^{3}}{3}. Multiply 2 times \frac{x^{3}}{3}.
\frac{2x^{3}}{3}-\frac{3x^{2}}{2}+\int -2\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}. Multiply -3 times \frac{x^{2}}{2}.
\frac{2x^{3}}{3}-\frac{3x^{2}}{2}-2x
Find the integral of -2 using the table of common integrals rule \int a\mathrm{d}x=ax.
\frac{2}{3}\times 3^{3}-\frac{3}{2}\times 3^{2}-2\times 3-\left(\frac{2}{3}\times 0^{3}-\frac{3}{2}\times 0^{2}-2\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.
-\frac{3}{2}
Simplify.
