integral of (10)/((1+x)^2)

\int \frac{10}{( 1 + x ) ^{2}} d x

- \frac{10}{1 + x} + C

Solution steps

\int \frac{10}{( 1 + x ) ^{2}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10 \cdot \int \frac{1}{( 1 + x ) ^{2}} d x

Apply u-substitution

: \int \frac{1}{u ^{2}} d u

= 10 \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= 10 (- \frac{1}{u})

Substitute back

u = 1 + x

= 10 (- \frac{1}{1 + x})

Simplify

10 (- \frac{1}{1 + x}) : - \frac{10}{1 + x}

= - \frac{10}{1 + x}

Add a constant to the solution

= - \frac{10}{1 + x} + C

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

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

\int (1 - x^{2})^{8} d x

\int (x + 3)^{5} d x

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