I guess the answer could be this:

10√15 - 2√15

Am I correct?

See WolframAlpha's various solutions here:

I don't believe yours is correct.... it would simplify to :  8√15

I believe I have settled this one. The issue is interpretation-based.

Cphill's interpretation: $$4\sqrt{15}-\textcolor{red}{\frac{10\sqrt{3}}{5}}+3\sqrt{60}$$

ManuelBautista2019: $$4\sqrt{15}-\textcolor{red}{10\sqrt{\frac{3}{5}}}+3\sqrt{60}$$

According to my individual calculation, both of you got the correct answer, assuming your interpretation.
