integral of (3x+2)^{1/2}

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

\frac{2}{9} (3 x + 2)^{\frac{3}{2}} + C

Solution steps

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

Apply u-substitution

: \int \frac{u ^{\frac{1}{2}}}{3} d u

= \int \frac{u ^{\frac{1}{2}}}{3} d u

Take the constant out:

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

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

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= \frac{1}{3} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 3 x + 2

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

Simplify

\frac{1}{3} \cdot \frac{2}{3} (3 x + 2)^{\frac{3}{2}} : \frac{2}{9} (3 x + 2)^{\frac{3}{2}}

= \frac{2}{9} (3 x + 2)^{\frac{3}{2}}

Add a constant to the solution

= \frac{2}{9} (3 x + 2)^{\frac{3}{2}} + C

\int \frac{7}{1 + x ^{2}} d x

x \to 3 lim (x^{2} + 5)

\frac{( s - 5 )}{( s ^{2} + 4 s + 20 )}

y^{^{'}} + 8 y = 56

x \to - 2 + lim (\frac{1}{( x + 2 ) ^{2}})
