You can put this solution on YOUR website!
You can do this one in several ways:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could move the constant term to the other side by adding 6 to both sides, then take the square root. Just remember to consider both the positive and negative roots.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could use the quadratic formula with $\"a=1\"$ , $\"b=0\"$ , and $\"c=-6\"$ . Remember the quadratic formula is: $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could use the fact that $\"6=%28sqrt%286%29%29%5E2\"$ and factor the quadratic using the difference of two squares factorization. Then apply the Zero Product Rule. Personnally, I like this method best because it won't allow you to forget to consider the negative root and it isn't as messy as the quadratic formula.\r
