Question 426442
<pre>
Solve log base 6 of x + log base 6 of (x+16)=2

The other person is WRONG!! The solution set is NOT {{{ x=-8+- 2*sqrt(7)}}}.

Correct x-values are 2 and - 18, of which - 18 should be IGNORED, since it's an EXTRANEOUS solution!!

Equation to be solved: {{{x^2 + 16x - 36 = 0}}}, which factors to (x - 2)(x + 18) = 0

You can do the check to CONFIRM!</pre>
