y^2+6y+10=0
\n" ); document.write( "y^2+6y = -10
\n" ); document.write( "take 1/2 'b', square it and add to both sides:
\n" ); document.write( "y^2+6y+3 = -10+3
\n" ); document.write( "(y+3)(y+3) = -7
\n" ); document.write( "(y+3)^2 = -7
\n" ); document.write( "y+3 = sqrt(-7)
\n" ); document.write( "y = sqrt(-7) - 3
\n" ); document.write( "y = +-sqrt(-7) - 3
\n" ); document.write( "Note: solution is imaginary (not real)\r
