Question 631058
{{{  2m^2 - 18m*n + 36n^2 = 0 }}}
{{{ m^2 - 9m*n + 18n^2 = 0 }}}
{{{ ( m - 6n )*( m - 3n ) = 0 }}}
check:
{{{ m = 6n }}}
{{{ m = 3n }}}
{{{  2*(6n)^2 - 18*(6n)*n + 36n^2 = 0 }}}
{{{ 2*36n^2 - 18*6n^2 + 36n^2 = 0 }}}
{{{ 72n^2 - 108n^2 + 36n^2 = 0 }}}
{{{ 108n^2 - 108n^2 = 0 }}}
OK
You can check {{{ m = 3n }}}
