\n" ); document.write( "5x^2-30x=-40
\n" ); document.write( "x^2-6x=-8
\n" ); document.write( "x^2-6x+9=-8+9
\n" ); document.write( "Factor to get:
\n" ); document.write( "(x-3)^2 = 1
\n" ); document.write( "Take the square root of both sides to get;
\n" ); document.write( "x-3=1 or x-3=-1
\n" ); document.write( "x = 4 or x = 2
