Question 85532
I'm not sure is one-half x squared is
{{{x^2/2}}} or {{{(x/2)^2}}}
If it's {{{x^2/2}}}, then the difference is {{{x^2/2}}}
But, if it's {{{(x/2)^2}}}, and I suspect it is, the
difference is
{{{x^2 - (x/2)^2}}}
{{{x^2 - x^2/4}}}
{{{3x^2/4}}} answer
This is easy to see if you just say {{{x^2 = y}}}, then
{{{y - y/4 = 3y/4}}}
