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

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

\frac{x ^{4}}{4} + \frac{7}{x} + C

Solution steps

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

Expand

\frac{x ^{5} - 7}{x ^{2}} : x^{3} - \frac{7}{x ^{2}}

= \int x^{3} - \frac{7}{x ^{2}} 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^{3} d x - \int \frac{7}{x ^{2}} d x

\int x^{3} d x = \frac{x ^{4}}{4}

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

= \frac{x ^{4}}{4} - (- \frac{7}{x})

Simplify

= \frac{x ^{4}}{4} + \frac{7}{x}

Add a constant to the solution

= \frac{x ^{4}}{4} + \frac{7}{x} + C

\int 1 d e^{- x^{2}}

\int x^{2} d x

\int \frac{x ^{5} + 3}{x ^{3} - 4 x} d x

\int \frac{( 3 x ^{2} - 4 x + 5 )}{( x - 1 ) ( x ^{2} + 1 )} d x

\int \frac{1}{x + 1 + x + 1} d x
