integral of 2sqrt(x^2)

\int 2 x^{2} d x

x^{2} + C

Solution steps

\int 2 x^{2} d x

Take the constant out:

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

= 2 \cdot \int x^{2} d x

x^{2} = (x),

assuming

x \geq 0

= 2 \cdot \int x d x

Apply the Power Rule

= 2 \cdot \frac{x ^{2}}{2}

Simplify

2 \cdot \frac{x ^{2}}{2} : x^{2}

= x^{2}

Add a constant to the solution

= x^{2} + C

\int ln (4) x^{2} d x

\int \frac{( e ^{u} )}{( 4 - e ^{u} ) ^{2}} d u

\int \frac{1}{( 16 - x ^{2} ) ^{\frac{5}{2}}} d x

\int 4 t + 0 d t

\int (5 x - 4)^{5} d x
