-1/2x²+4x-6=0
\n" ); document.write( "Multiply thru by -2 to get:
\n" ); document.write( "x^2-8x+12 = 0
\n" ); document.write( "Complete the square on the x terms and keep the equation balanced.
\n" ); document.write( "----------
\n" ); document.write( "x^2-8x = -12
\n" ); document.write( "x^2-8x+16 = -12+16
\n" ); document.write( "(x-4)^2 = 4
\n" ); document.write( "--------------
\n" ); document.write( "Take the square root of both sides to get:
\n" ); document.write( "x-4 = 2 or x-4 = -2
\n" ); document.write( "x = 6 or x = 2
