True/False

A civil engineer is modeling the internal stress on a steel beam using the equation log3x+log3(x8)=2\log_3 x + \log_3(x-8) = 2, where xx represents the stress level. True or False: While solving this equation yields the potential values x=9x = 9 and x=1x = -1, the engineer must reject x=1x = -1 as an extraneous solution because the argument of a logarithm must be a positive number.
