Question 1085109
{{{ x*(x+66) = 135135 }}}
{{{  x^2 + 66x - 135135 = 0 }}}
{{{ x = ( -66 +- sqrt(66^2 - 4*(1)(-135135) )) / 2  }}}
{{{ x =  -33 +- sqrt(544896)/2  }}}
{{{ x = -33 +- 369.085356 }}}
{{{ x = 336.085356 }}}  and {{{ x = -402.085356 }}}
—

So those are the 'x' values, each gets paired with 'x+66':
—
Solutions are ( 336.085356 and 402.085356 )
and  ( -402.085356 and -336.085356 )
