\frac{1}{3}x^{2}x+2x^{2}+3x
Multiply x and x to get x^{2}.
\frac{1}{3}x^{3}+2x^{2}+3x
To multiply powers of the same base, add their exponents. Add 2 and 1 to get 3.
\frac{xxx+6x^{2}+9x}{3}
Factor out \frac{1}{3}.
x\left(x^{2}+6x+9\right)
Consider x^{3}+6x^{2}+9x. Factor out x.
\left(x+3\right)^{2}
Consider x^{2}+6x+9. Use the perfect square formula, a^{2}+2ab+b^{2}=\left(a+b\right)^{2}, where a=x and b=3.
\frac{x\left(x+3\right)^{2}}{3}
Rewrite the complete factored expression.
