Question Regarding Logs specifically logs with $x$s involved

Question

$$\log(5x + 5) = 2\log(x + 1)$$

Thats the original question. So far I have gotten.

$$\log(5x + 5) = \log(x + 1)^2$$

I am not looking for the answer maybe just a hint in the right direction.

Thanks!

Answer 1

Hint:

A logarithm is an injective function, which means that if $\log(a)=\log(b)$, then $a=b$.

Just be careful, that $\log(a)=\log(b)$ also implicitly means that $a,b>0$.
