gollark: Anyway! You would probably use a calculator, which contains the formula. Or guess a factor and use polynomial division. Or use numerical methods to approximately get a solution.
gollark: There are none above this due to something called Galois theory, which I don't understand and which is something something abstract algebra something something polynomials.
gollark: There is also a quartic (degree 4 polynomial) formula. This is somehow even worse.
gollark: You will never be asked to memorise it because that would be stupid.
gollark: Yes, but ridiculously big.
