Multiple Choice

A solar energy consultant uses the equation 1−5y=−6y21 - \frac{5}{y} = -\frac{6}{y^2} to model the energy output of a power system. After transforming the equation into the factored form (y−2)(y−3)=0(y - 2)(y - 3) = 0, the consultant must determine the values for yy. Which mathematical property is specifically recalled and applied at this step to conclude that y−2=0y - 2 = 0 or y−3=0y - 3 = 0?
