How to solve a 3rd degree polynomial
WebFor polynomial of degree 3 you can use the following procedure. Assume that you guessed the solution x 1 = 4 (indeed 4 3 − 6 ⋅ 4 2 − 2 ⋅ 4 + 40 = 64 − 96 − 8 + 40 = 0). You can use … WebJun 15, 2024 · You should check that r3 = 3 really is a root. Hence we know that e − x, ex, and e3x are solutions to (2.3.2). They are linearly independent as can easily be checked, and there are three of them, which happens to be exactly the number we need. Hence the general solution is y = C1e − x + C2ex + C3e3x
