Oh... I was thinking about differential equations😂 I'm not really sure how to do it, maybe try converting it to (x-a)(x-b)(x-c)(x-d)=0 and solve a,b,c,d?🤔

Try all factors of 354

It's Newton's method, used to find rational roots

Flandre scarlet, is there any method to find all roots of a function at once?

What if the equation resembles something like this '8x^4-54x^3+101x^2-54x+8=0'? Will the factoring method work here with this too? Or synthetic division? Flandre scarlet?

Synthetic division helps right? Except that we have to merge the use of quadratic root finding method to get to the final solution.
