For maths, numerical recipes and wolfram is always the goto
GitHub - sasamil/Quartic: Solving algebric equation of 4th order. Fast and efficient. C++ implementation.[^]
Read the docx file to understand it but it sort of follow this form
Math Forum - Ask Dr. Math[^]
The code isn't great like returning an allocated memory block ... I would rework it.

You can solve them online on wolfram .. try an example like
solve x^4 + 12*x^3 + 7*x^2 + 2*x + 12 = 0
https://www.wolframalpha.com/input/?i=solve+x%5E4+%2B+12*x%5E3+%2B+7*x%5E2+%2B+2*x+%2B+12+%3D+0[^]
It's useful to check your code
