Answer 2

Answer:

x2+6x+9x2–9=(x+3)2(x−3)(x+3)=x+3x−3

log(x2+6x+9x2−9)=log(x+3x−3)

I’m not sure what you’re trying to solve, since there is no equation to solve.

Perhaps you need to expand by splitting into 2 logs?

If so, use the formula: log(a/b) = log(a) - log(b).

So we get: log(x+3)−log(x−3)

However, if we try to graph all 3 function, we will find that the first 2 have the same domain: (−∞,−3)∪(3,∞), but the 3rd function has domain (3,∞).

We can get around this by taking absolute values: log|x+3|−log|x−3|

But now domain is (−∞,−3)∪(−3,3)∪(3,∞).

To get around this, we must specifically state domain for new expression:

log(x2+6x+9x2−9)=log|x+3|−log|x−3||x|>3
