\int 7x+5\mathrm{d}x
Evaluate the indefinite integral first.
\int 7x\mathrm{d}x+\int 5\mathrm{d}x
Integrate the sum term by term.
7\int x\mathrm{d}x+\int 5\mathrm{d}x
Factor out the constant in each of the terms.
\frac{7x^{2}}{2}+\int 5\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 7 times \frac{x^{2}}{2}.
\frac{7x^{2}}{2}+5x
Find the integral of 5 using the table of common integrals rule \int a\mathrm{d}x=ax.
\frac{7}{2}\times 2^{2}+5\times 2-\left(\frac{7}{2}\times 0^{2}+5\times 0\right)
