Question 153942
{{{m^2-(25/2)*m=5/2}}}
{{{m^2-2(25/4)m=5/2}}}
{{{m^2-2(25/4)m+(25/4)^2=5/2+(25/4)^2}}}
{{{(m-25/4)^2=5/2+(25/4)^2}}}
{{{(m-25/4)^2=5/2+625/16}}}
{{{(m-25/4)^2=(5*8)/(2*8)+625/16}}}
{{{(m-25/4)^2=(5*8)/(2*8)+625/16}}}
{{{(m-25/4)^2=40/16+625/16}}}
{{{(m-25/4)^2=665/16}}}
{{{m=25/4+-sqrt(665/16)}}}
{{{m=25/4+-sqrt(665)/4}}}
