Hello,
\n" ); document.write( "With this x^2+3x-6 x=-4 we combine like terms and add 4:
\n" ); document.write( "x^2-3x+4=0
\n" ); document.write( "Factor this using quadratic formula:
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt%28+9-4%2A1%2A4+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt-7%29%2F2+\"$
\n" ); document.write( "We have an imaginary number written as:
\n" ); document.write( "x = (3+-i sqrt 7 )/2
\n" ); document.write( "Make sense?
