Cubic polynomials can be solved in the similar manner as quadratic equations. But to make it to a much simpler form, we can use some of these special products: 1. Perfect cube (2 forms): a3 ± 3a2b + 3ab2 ± b3 = (a ± b)3 2. Difference of the cubes: a3 − b3 = (a − b)(a2 + ab +b2) 3. Sum of the cubes: a3 + b3 = (a + … See more The cubic polynomial formula is in the general form of ax3 + bx2 + cx + d and the formula for the solution of the cubic equation is ax3 + … See more Synthetic divisionis a method used to perform the division operation on polynomials when the divisor is a linear factor.

Quartic Equation -- from Wolfram MathWorld
WebSo the hardest part of factoring a cubic polynomial in general is finding a real root. Once a root r r is found, the polynomial factors as f (x) = (x-r)g (x), f (x) = (x−r)g(x), where g (x) g(x) is quadratic, and quadratic polynomials can be factored easily via the quadratic formula. Techniques for finding a real root of a cubic polynomial ... WebMar 24, 2024 · A quartic equation is a fourth-order polynomial equation of the form z^4+a_3z^3+a_2z^2+a_1z+a_0=0. (1) While some authors (Beyer 1987b, p. 34) use the term "biquadratic equation" as a synonym for quartic equation, others (Hazewinkel 1988, Gellert et al. 1989) reserve the term for a quartic equation having no cubic term, i.e., a … diamonds direct cleveland beachwood
