Step 1
To evaluate the given integrals.
Step 2
Given that
\(\displaystyle=\int{\left({2}{x}^{{{3}}}-{x}^{{{2}}}+{3}{x}-{7}\right)}{\left.{d}{x}\right.}\)
\(\displaystyle=\int{2}{x}^{{{3}}}{\left.{d}{x}\right.}-\int{x}^{{{2}}}{\left.{d}{x}\right.}+\int{3}{x}{\left.{d}{x}\right.}-\int{7}{\left.{d}{x}\right.}\)
\(\displaystyle={\frac{{{2}{x}^{{{4}}}}}{{{4}}}}-{\frac{{{x}^{{{3}}}}}{{{3}}}}+{\frac{{{3}{x}^{{{2}}}}}{{{2}}}}-{7}{x}+{c}\)
\(\displaystyle={\frac{{{x}^{{{4}}}}}{{{2}}}}-{\frac{{{x}^{{{3}}}}}{{{3}}}}+{\frac{{{3}{x}^{{{2}}}}}{{{2}}}}-{7}{x}+{c}\)
