in this exercise. We just want to find the values of the variables for which this rational expressions on the find and I'll have to do for this. It's a regional mayor equal to zero, so we'll have to. A minus seven equals zero at seven full size, we get to a vehicle seven divide by two when we get a equals seven over to so that we can say that a cannot equal seven over to If we want to have this expression be defined because of equal seven over to, we're gonna zero in the denominator and therefore it is undefined.
