24-6x^2=0 -complete the square
\n" ); document.write( "since there is no x-term, can't complete the square.
\n" ); document.write( "..
\n" ); document.write( "x^2-x-4=8 complete the square
\n" ); document.write( "Take 1/2 the coefficient of the x-term, then add its square. Add the same amt to other side of equation to maintain equality.
\n" ); document.write( "(x^2-x+1/4)=12+1/4 (add 1/4 to maintain equality)
\n" ); document.write( "(x-1/2)^2=49/4
\n" ); document.write( "..
\n" ); document.write( "-3x^2=7x+2 complete the square
\n" ); document.write( "-3x^2-7x=2
\n" ); document.write( "-3(x^2-7x/3+49/36)=2-49/12 (add -3*49/36=-49/12 to maintain equality)
\n" ); document.write( "-3(x-7/6)^2=-25/12
\n" ); document.write( "
\n" );
