A problem I am very stuck on and need help!

Non-negative real numbers $a, b$ and $c$ satisfy $$a^2+b^2+c^2+70=35ab+7ac+5bc.$$
The least possible value of $a^2+2b^2+3c^2$ can be expressed as $\frac{m}{n}$ where $m$ and $n$ are relatively prime positive integers. FInd $m+n$

But I don't know what you mean by bc-inversion, since I have never studied inversion.

Is there a solution to problem 1 without inversion? I don't really know inversion, like is there an angle chasing solution? If so can you post a solution?
