Since the degrees of the terms are all even, this is a quartic equation.
Unfortunately, there is no simple way to solve a quartic equation. You can either try to factorize the equation or use numerical methods to find approximate solutions.
If you have a specific value for x that you would like to substitute in and check the validity of the equation, please provide it.
To solve the given equation:
(x^2 - 4)^2 + (x^2 - 6x - 16)^2 = 0
Let's first expand the squares:
(x^4 - 8x^2 + 16) + (x^4 - 12x^3 + 36x^2 - 12x^2 + 72x + 256) = 0
Combine like terms:
2x^4 - 20x^2 - 12x^3 + 72x + 272 = 0
Rearrange the terms to get a simpler form:
2x^4 - 12x^3 - 20x^2 + 72x + 272 = 0
