So let's see where it equals zero. So let's set it equal to zero. Three x squared minus 24 x plus 48 is equal to zero. Let's see, everything is divisible by three, so let's divide everything by three. So you get x squared minus eight x plus 16, plus 16 is equal to zero, and let's see, can I factor this? Yeah, this would be x minus four times x minus four. Or I could just do this as x minus four squared is equal to zero, or x minus four is equal to zero, so, or where x equals four.
