6.4 Logarithmic Equations and Inequalities
www.shsu.eduwhen solving equations involving logarithms. Even though we checked our answers graphically, extraneous solutions are easy to spot - any supposed solution which causes a negative number inside a logarithm needs to be discarded. As with the equations in Example6.3.1, much can be learned from checking all of the answers in Example6.4.1analytically.
