move constant terms to right side ... \"x%5E2%2B6x=40\"\r
\n" ); document.write( "\n" ); document.write( "divide the coefficient of the x term by 2, square it, and add to both sides ... \"x%5E2%2B6x%2B3%5E2=40%2B3%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factor the quadratic ... \"%28x%2B3%29%5E2=49\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "take the square root of both sides ... x+3=7 and x+3=-7 ... so x=4 and x=-10
\n" ); document.write( "
\n" );
