Which of the following shows the extraneous solution to the logarithmic equation log Subscript 7 Baseline (3 x cubed + x) minus log Subscript 7 Baseline (x) = 2 x = negative 16 x = negative 4 x = 4 x = 16

Step-by-step explanation:

A graphing calculator shows there is one solution to ...

However, the usual solution method would be to combine the logarithms and take the antilog to get ...

This gives two solutions. the "solution" x = -4 is extraneous, as it doesn't work in the original equation. "x" must be positive in the log expressions.

x = - 4
