Solving a depressed cubic
WebSolving Cubic Equations First, write your equation as a polynomial: A V3 + B V2 + C V + D = 0 Method 1: Iteration 1.) Write the equation as V=f(V) V = -(1/C) (A V3 + B V2 + D) ... Excel will then numerically solve for a value of A2 that will cause B2 to equal 0. Since it solves numerically, it will reach 0 to within some very some value (10-4) http://www.sosmath.com/algebra/factor/fac11/fac11.html

WebJan 31, 2024 · Now, we can solve the equation using any appropriate method. A cubic equation can be solved in the following ways: Finding Integer Solutions with Factor Lists; Using the Graphical method; Solving the cubic equation using factors of the polynomial. Example: Find the roots of equation f(x) = 3x 3 −16x 2 + 23x − 6 = 0. Solution: WebOct 11, 2024 · Well, a depressed cubic as you put it; has no quadratic part (no x 2 term). The trick here is to realise that when you are trying to find its root, you are solving the equation: a x 3 + b x + c = 0. You'll see that if you substitute: y = x 3. you'll just get: a ( x 3) + b x + c = a … Note that, if a polynomial has a complex root, then its complex conjugate is also a …

Then his assis-tant Lodovico Ferrari extended this string of discoveries by solving fourth-degree problems, but both men refrained from publishing their results because they were based on Tartaglia's solution.
WebCubic Discriminant. We can compute the discriminant of any power of a polynomial. For example, the quadratic discriminant is given by \Delta_2 = b^2 - 4ac Δ2 = b2 −4ac. But it gets more complicated for higher-degree polynomials. The discriminant of a cubic polynomial ax^3 + bx^2 + cx + d ax3 +bx2 +cx +d is given by.
