6 = sqrt( (x - 3)(x - 3) + (-9 + 5)(-9 + 5) )
\n" ); document.write( "36 = (x - 3)(x - 3) + (-4)(-4)
\n" ); document.write( "36 - 16 = xx - 6x + 9
\n" ); document.write( "20 = xx - 6x + 9
\n" ); document.write( "xx - 6x - 11 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=1, b=-6, and c=-11
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, copy and paste this:
\n" ); document.write( "1 -6 -11

\n" ); document.write( "x = -1.47213595
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "either value of x satisfies the requirement:
\n" ); document.write( "x = 7.47213595
