Now we bring everything to one side, and we equate it to zero. So we want a positive X squared, because it's easier to work with. So we bring these guys over on this side. So X squared plus 1.8
times ten to the negative five. Because when we bring this guy over, this becomes a positive minus, because this guy was initially a plus. So when we bring it over, it will be a -3.6
times ten to the negative seven equals zero.
