A couple of ways...let me show you how to do it without using the quadratic formula...notice the left side is a perfect square...let's take advantage of that...we get
\n" ); document.write( "x^2 + 4x + 4 = 7
\n" ); document.write( "(x + 2)^2 = 7
\n" ); document.write( "x + 2 = ± sqrt(7)
\n" ); document.write( "x = -2 ± sqrt(7)
\n" ); document.write( "and we're done...
\n" ); document.write( "
