The equation is .

Solve the equation.

           (Original equation)

                              (Logarithm formula: if and only if )

              (Subtract from each side)

                         (Apply additive inverse property:) 

                 (Factors)

              (Group of the factors)

                        (Take out the common factors)

or                   (Zero product property:)

or                           (Simplify)

Check solution for -values.

Case (i):

                 (Original equation)

      (Substitute )

                 (Evaluate powers)

                      (Subtract: )

Case (ii):

                 (Original equation)

            (Substitute )

                 (Evaluate powers)

                         (Subtract: )

The values are or .

Since is undefined, So is an extraneous solution.

The solution is .

Option C is the right answer.
