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 WebHow To: Given a factor and a third-degree polynomial, use the Factor Theorem to factor the polynomial. Use synthetic division to divide the polynomial by [latex]\left(x-k\right)[/latex]. ... This theorem forms the foundation for solving polynomial equations. Suppose f is a polynomial function of degree four and [latex]f\left(x\right)=0[/latex ...
Web3 You need to solve the equation x 5 + 2 x 3 + x − 1 = y for x. Unfortunately, such quintic equations are known to have no closed-form solution in general, and this one does not escape the rule. Anyway, there is a little backdoor, as a quintic can be (after painful computation) reduced to the form known as Bring Quintic Form x 5 − x − a = 0.
