integral of (12-12x)/(1-sqrt(x))

\int \frac{12 - 12 x}{1 - x} d x

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

Solution steps

\int \frac{12 - 12 x}{1 - x} d x

Apply u-substitution

: \int 24 u (u + 1) d u

= \int 24 u (u + 1) d u

Take the constant out:

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

= 24 \cdot \int u (u + 1) d u

Expand

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

= 24 \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

= 24 (\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}

= 24 (\frac{u ^{3}}{3} + \frac{u ^{2}}{2})

Substitute back

u = x

= 24 (\frac{( x ) ^{3}}{3} + \frac{( x ) ^{2}}{2})

Simplify

24 (\frac{( x ) ^{3}}{3} + \frac{( x ) ^{2}}{2}) : 24 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2})

= 24 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2})

Add a constant to the solution

= 24 (\frac{1}{3} x^{\frac{3}{2}} + \frac{x}{2}) + C

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

X^{2} - 2 X - 15

\int 7 x^{4} d x

f (x) = 7 x^{2} + 5 x - 8

x \to 0 lim (\frac{3}{sin ( 3 x )})
