Answer:

I am adding my calculations hope that helps

Take lcm

Let

(a + b)(a + c) = p \\ (b + c)(b + a) = q \\ (c + a)(c + b) = r

4 {a}^{2} (a + c)(b + c) + 2 {a}^{2}( b + a)(c + a) \\  = 2 {a}^{2} (a + c)(a + 3b + 2c) \\   =    2 {a}^{2} (p + q + r)

Similarly other terms

and your fraction becomes

 \frac{ {x}^{2}(p + q + r) - 2 {a}^{2} (p + q + r) - 2 {b}^{2} (q + p + r) - 2 {c}^{2} (r + q + p) }{ \sqrt{pqr} }  = 0 \\   \\ (p + q + r)( {x}^{2}  - 2 {a}^{2}  -  2{b}^{2}  - 2 {c}^{2} ) = 0 \\ x =  \pm \sqrt{2( {a}^{2} +  {b}^{2}   +  {c}^{2} )}
