\( \frac{5x^4}{4} + \frac{7x^3}{3} + 2x + C \)
\( \frac{5x^4}{4} + \frac{7x^3}{3} - x^2 + 5x + C \)
\( \frac{5x^3}{3} + \frac{7x^2}{x} - x + C \)
\( \frac{2x^2}{3} + \frac{x}{5} - C \)
Correct answer is B
\(\int (5x^{3} + 7x^{2} - 2x + 5) \mathrm d x\)
= \(\frac{5x^{4}}{4} + \frac{7x^{3}}{3} - \frac{2x^{2}}{2} + 5x + c\)
= \(\frac{5x^{4}}{4} + \frac{7x^{3}}{3} - x^{2} + 5x + c\)
