Can a minus sign be moved to the front of a rational expression?
In order to move a minus sign to the front of a rational expression it needs to be times the whole numerator or denominator. So, if we factor a minus out of the numerator we could then move it into the front of the rational expression as follows, The moral here is that we need to be careful with moving minus signs around in rational expressions.
