Math Problem Statement
Solution
We are given the equation:
Step 1: Remove the logarithms
Since the base of the logarithm on both sides is the same (base 5), we can equate the arguments inside the logarithms:
Step 2: Solve the quadratic equation
Rearrange the equation into standard quadratic form:
Now, factor the quadratic:
Step 3: Solve for
Set each factor equal to zero:
Step 4: Check for extraneous solutions
For logarithmic equations, it's important to check that the solutions do not result in taking the logarithm of a negative number or zero.
- For : , so both sides of the original equation are valid.
- For : , so both sides of the original equation are valid.
Thus, both solutions are valid.
Final Answer:
The solutions are and .
