Question 56917
You must need to expand or simplify this.  You didn't include your directions.
{{{3x(x^(1/2)+1)^2}}}
{{{3x(x^(1/2)+1)(x^(1/2)+1)}}}
{{{3x(x^(1/2)(x^(1/2))+x^(1/2)(1)+1(x^(1/2))+1(1))}}}
{{{3x(x^(2/2)+x^(1/2)+x^(1/2)+1)}}}
{{{3x(x+2x^(1/2)+1)}}}
{{{3x(x)+3x(2x^(1/2))+3x(1)}}}
{{{3x^2+6x^(1+1/2)+3x}}}
{{{3x^2+6x^(2/2+1/2)+3x}}}
{{{3x^2+6x^(3/2)+3x}}}
Happy Calculating!!!
