Como elaborar uma equação cubica de uma raiz





Como elaborar uma equação cúbica de uma raiz

Elaborar uma equação cúbica cuja raiz seja 7:

(x+b)n = m

(x-3)3 = 64

(x-b)3 = x3- 3x2b+3xb2-b3

(x-3)3 = x3 – 3x2 * 3 + 3x * 9 – 27 = 64


x3 - 9x2 + 27x – 91 = 0






The formulas of R. S. Chaves solve: cubic equations, quartic equations and quintic equations. Read the book: Cartilha das Equações (formulas of R. S. Chaves), published in the Amazon stores in e-Book Kindle.
The book contains unpublished formulas for cubic equation, quartic equation, and quintic equation. The demonstration of the formulas is published in the book. It was released on August 16, 2018.
For hundreds of years mathematicians seek formulas to solve cubic equation and quartic equation. They are in the book. The way these formulas have been developed may inspire mathematicians to develop new formulas. Amazon lets you read the first few pages of the book before you buy it. Take a look and you'll see it's worth it. In Amazon search look for: "R. S. Chaves" or "Cartilha das Equações"
