Question 974783
{{{y^2+6x+12y-6=0}}}
{{{y^2+12y+6x-6=0}}}
{{{y^2+12y+(6x-6)=0}}}

a=1, b = 12, c = (6x-6)

{{{y}}}{{{""=""}}}{{{(-b +- sqrt( b^2-4ac ))/(2a) }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(12^2-4(1)(6x-6) ))/(2(1)) }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(144-4(6x-6) ))/2 }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(144-24x+24 ))/2 }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(168-24x))/2 }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(24(7-x)))/2 }}}

{{{y}}}{{{""=""}}}{{{(-12 +- sqrt(4*6(7-x)))/2 }}}

{{{y}}}{{{""=""}}}{{{(-12 +- 2*sqrt(6(7-x)))/2 }}}

{{{y}}}{{{""=""}}}{{{(2(-6 +- sqrt(6(7-x))))/2 }}}

{{{y}}}{{{""=""}}}{{{(cross(2)(-6 +- sqrt(6(7-x))))/cross(2) }}}

{{{y}}}{{{""=""}}}{{{-6 +- sqrt(6(7-x)) }}}
