You can put this solution on YOUR website!
2x^2 + 2x +10 = 0
\n" ); document.write( ":
\n" ); document.write( "divide both sides of = by 2
\n" ); document.write( ":
\n" ); document.write( "x^2 +x +5 = 0
\n" ); document.write( ":
\n" ); document.write( "solve by completing the square
\n" ); document.write( ":
\n" ); document.write( "x^2 +x + 1/4 = -5 + 1/4
\n" ); document.write( ":
\n" ); document.write( "(x + 1/2)^2 = -19/4
\n" ); document.write( ":
\n" ); document.write( "take square root of both sides of =
\n" ); document.write( ":
\n" ); document.write( "x + 1/2 = square root(-19/4)
\n" ); document.write( ":
\n" ); document.write( "the solution is two complex numbers
\n" ); document.write( ":
