Assuming that the left side is a determinant, and expanding it by the first column, we get
=(b2+c2)[(c2+a2)(a2+b2) - (bc)2] - ab[ab(a2+b2) - ac(bc)] +ac[ab(bc) - ac(c2+a2)]
which I ask you to multiply out, carefully, to finish the job. It's easier to do on paper than to type in!
YOU CAN DO IT!

"Elimination" is not applicable in this case.
Elimination is a method (hand-crafting) to solve a systemof simultaneous equations.
But this problem is an IDENTITY--you need to do the Algebra to evaluate the left side expression & show that, when simplified, you get the result that is on the right side of the equation.
