\n" ); document.write( "\n" ); document.write( "Assuming that the coefficient of \"x%5E2\" is 1, you must take HALF of the x coefficient and SQUARE it, adding this quantity to each side of the equation as follows:\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2+%2B4x+%2B_____=+6+%2B+____\" Half of 4 is 2, and 2^2= 4!
