$\"+x%5E2%2B7x%2B9=0+\"$
\n" ); document.write( "this is in the form
\n" ); document.write( "ax^2 + bx + c = 0
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "this will find the roots at the points (r(1), 0) and (r(2),0)
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%28+7%5E2-4%2A1%2A9+%29%29%2F%282%2A1%29+\"$
