[tex]a) \\ = \frac{7}{0 + 1} {x}^{0 + 1} - \frac{3}{2 + 1} {x}^{2 + 1} + c = 7x - {x}^{3} + c[/tex]
[tex]b) \\ = \frac{3}{2 + 1} {x}^{2 + 1} + \frac{2}{1 + 1} {x}^{1 + 1} - \frac{1}{0 + 1} {x}^{0 + 1} + c \\ = {x}^{3} + {x}^{2} - x + c[/tex]
[tex]c) \\ = \frac{5}{0 + 1} {x}^{0 + 1} - \frac{1}{1 + 1} {x}^{1 + 1} + \frac{1}{2 + 1} {x}^{2 + 1} - \frac{1}{3 + 1} {x}^{ 3 + 1} + \frac{1}{4 + 1} {x}^{4 + 1} + c \\ = 5x - \frac{1}{2} {x}^{2} + \frac{1}{3} {x}^{3} - \frac{1}{4} {x}^{4} + \frac{1}{5} {x}^{5} + c[/tex]
[tex]d) \\ = \frac{100}{4 + 1} {x}^{4 + 1} - \frac{60}{3 + 1} {x}^{3 + 1} + \frac{30}{2 + 1} {x}^{2 + 1} - \frac{10}{1 + 1} {x}^{1 + 1} + \frac{1}{0 + 1} {x}^{0 + 1} + c \\ = 20 {x}^{5} - 15 {x}^{4} + 10 {x}^{3} - 5 {x}^{2} + x + c[/tex]
[tex]e) \\ integral \: \: ({x}^{2} - 1)dx \\ = \frac{1}{2 + 1} {x}^{2 + 1} - \frac{1}{0 + 1} {x}^{0 + 1} + c \\ = \frac{1}{3} {x}^{3} - x + c[/tex]
