integral of (x^2-7x+5)

\int (x^{2} - 7 x + 5) d x

\frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 5 x + C

Solution steps

\int x^{2} - 7 x + 5 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x^{2} d x - \int 7 x d x + \int 5 d x

\int x^{2} d x = \frac{x ^{3}}{3}

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 5 d x = 5 x

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 5 x

Add a constant to the solution

= \frac{x ^{3}}{3} - \frac{7 x ^{2}}{2} + 5 x + C

\frac{d}{d x} (\frac{4 - 2 x - x ^{3}}{3 x - x ^{4}})

y = 0, y = 9 - x^{2}, y = 0

f (x) = \frac{1}{x ^{4}}, (3, \frac{1}{81})

\int \frac{\frac{4}{x ^{3}} + 2}{\frac{1}{x ^{2}} - x} d x

\frac{d y}{d x} + 2 y = 1
