Question 1061654
To avoid confusion, I'll use capital A
{{{ x^2 + x = A^2 + A }}}
{{{ x^2 + x - ( A^2 + A ) = 0 }}}
{{{ x = ( -b +- sqrt( b^2 - 4*a*c ))/(2*a) }}}
{{{ a = 1 }}}
{{{ b = 1 }}}
{{{ c = A^2 + A }}}
{{{ x = ( -1 +- sqrt( 1^2 - 4*1*(A^2 + A) ))/(2*1) }}}
{{{ x = ( -1 +- sqrt( 1 - 4*(A^2 + A) ))/2 }}}
{{{ x = ( -1 +- sqrt( 1 - 4A^2 - 4A) ))/2 }}}
{{{ x = ( -1 +- sqrt( - 4A^2 - 4A + 1 ) ))/2 }}}
Check my math & maybe get another opinion
