integral of ((12x+1))/(sqrt(4x-3))

\int \frac{( 12 x + 1 )}{4 x - 3} d x

\frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3) + C

Solution steps

\int \frac{12 x + 1}{4 x - 3} d x

Apply u-substitution

= \int \frac{3 u ^{2} + 10}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int 3 u^{2} + 10 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

= \frac{1}{2} (\int 3 u^{2} d u + \int 10 d u)

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

\int 10 d u = 10 u

= \frac{1}{2} (u^{3} + 10 u)

Substitute back

u = 4 x - 3

= \frac{1}{2} ((4 x - 3)^{3} + 10 4 x - 3)

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

= \frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3)

Add a constant to the solution

= \frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3) + C
