This is a complete the square problem
\n" ); document.write( "2x^2 +4x - 4 = 0
\n" ); document.write( "divide by 2
\n" ); document.write( "x^2 + 2x - 2 = 0
\n" ); document.write( "now add -2 to both sides of =
\n" ); document.write( "x^2 +2x = 2
\n" ); document.write( "take 1/2 of 2 and square it, then add to both sides of =
\n" ); document.write( "x^2 +2x + 1 = 3
\n" ); document.write( "(x +1)^2 = 3
\n" ); document.write( "take square root of both sides of =
\n" ); document.write( "x+1 = square root(3)
\n" ); document.write( "x = square root(3) - 1
\n" ); document.write( "x = +square root(3) - 1
\n" ); document.write( "x = -square root(3) -1
\n" ); document.write( "To the student, remember when completing the square to move the loose number (-2) to the right of the equal sign and square root means + or - square root
\n" ); document.write( "
