When solving the equation log7 ⁡(x+1) + log7⁡x = log7⁡ 12 a student arrives at a verifiable solution and an extraneous solution. the value of the extraneous solution is

3

-4

-3

5.5

Step-by-step explanation:

The given logarithmic equation is:

Recall and apply product rule of logarithms.

We apply this property to the left side of the equation to get;

We take the antilogarithm of both sides to get:

We expand to obtain:

We rewrite in the standard quadratic form:

We factor to obtain:

Either or

Either or

But the domain is.

Hence is an extraneous solution.
