integral of (16-16x)/(1-sqrt(x))

\int \frac{16 - 16 x}{1 - x} d x

32 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2}) + C

Solution steps

\int \frac{16 - 16 x}{1 - x} d x

Apply u-substitution

: \int 32 u (u + 1) d u

= \int 32 u (u + 1) d u

Take the constant out:

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

= 32 \cdot \int u (u + 1) d u

Expand

u (u + 1) : u^{2} + u

= 32 \cdot \int u^{2} + u d u

Apply the Sum Rule:

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

= 32 (\int u^{2} d u + \int u d u)

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

\int u d u = \frac{u ^{2}}{2}

= 32 (\frac{u ^{3}}{3} + \frac{u ^{2}}{2})

Substitute back

u = x

= 32 (\frac{( x ) ^{3}}{3} + \frac{( x ) ^{2}}{2})

Simplify

32 (\frac{( x ) ^{3}}{3} + \frac{( x ) ^{2}}{2}) : 32 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2})

= 32 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2})

Add a constant to the solution

= 32 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2}) + C

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

x \to \infty lim (0. 3^{x})

f (x) = \frac{sin ( x )}{5 + 5 cos ( x )}, at x = \frac{π}{3}

\frac{s + 1}{s ^{2} + 2 s + s}

\frac{\partial}{\partial x} (\frac{6 x}{y})
