In algebra, a cubic equation in one variable is an equation of the form + + + = in which a is not zero. The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation.

A cubic equation is an algebraic equation of third-degree. The general form of a cubic function is: f (x) = ax 3 + bx 2 + cx 1 + d. And the cubic equation has the form of ax 3 + bx 2 + cx + d = 0, where a, b and c are the coefficients and d is the constant.

2024年4月28日 · Cubic Equation is a mathematical equation in which a polynomial of degree 3 is equated to a constant or another polynomial of maximum degree 2. The standard representation of the cubic equation is ax 3 +bx 2 +cx+d = 0 where a, b, c, and d are real numbers.

3 天之前 · The Wolfram Language can solve cubic equations exactly using the built-in command Solve [a3 x^3 + a2 x^2 + a1 x + a0 == 0, x]. The solution can also be expressed in terms of the Wolfram Language algebraic root objects by first issuing SetOptions [Roots, Cubics -> False].

A cubic equation is an equation which can be represented in the form \(ax^3+bx^2+cx+d=0\), where \(a,b,c,d\) are complex numbers and \(a\) is non-zero. By the fundamental theorem of algebra , cubic equation always has \(3\) roots, some of which might be equal.

2025年1月28日 · Q.1: What is a cubic equation formula? Ans: A cubic equation is an algebraic equation of degree three. The standard form of a cubic equation is defined as \(a{x^3} + b{x^2} + cx + d = 0,\) where \(a,b,c,d\) are integers and \(a\) is non-zero.

What is Cubic Equation Formula? To plot the curve of a cubic equation, we need cubic equation formula. This formula helps to find the roots of a cubic equation.

In 1545, Cardan (or Cardano) published methods to solve the cubic and quartic equations. His great achievement was to make public the work of others, which had been previously kept secret. This method is based on Cardan's published method. Consider the following equation:
