Question 819011: Write as a single logarithm and simplify: log_(2)(a+b)+log_(2)(a-b)-2log_(2)(a)
So far I've gotten log_(2)(a+b)(a-b)-log_(2)(a)^2
=log_(2)((a+b)(a-b))/(a^2)
I need help completing this.

Write as a single logarithm and simplify: log_(2)(a+b)+log_(2)(a-b)-2log_(2)(a)
------------------
log2[(a+b)(a-b)]-log2(a^2)
-------
= log2[(a^2-b^2)/a^2]
-------
