Question 1029520
{{{x(3x-7)=-3}}}
{{{3x^2-7x+3=0}}}
{{{3(x^2-(7/3)x)+3=0}}}
{{{3(x^2-(7/3)x+(7/6)^2)+3=3(7/6)^2}}}
{{{3(x-7/6)^2+3=3(49/36)}}}
{{{3(x-7/6)^2=147/36-108/36}}}
{{{3(x-7/6)^2=39/36}}}
{{{(x-7/6)^2=13/36}}}
{{{x-7/6=0 +- sqrt(13)/6}}}
{{{x=7/6 +- sqrt(13)/6}}}
{{{x=(7 +- sqrt(13))/6}}}
So,
{{{m=7}}}
{{{n=13}}}
{{{p=6}}}
{{{highlight(m+n+p=26)}}}
