A cubic equation is an algebraic expression that involves the variable of the highest degree as a cube. It has the general form ax^3 + bx^2 + cx + d = 0, where a, b, c, and d are constants and x ...

Simultaneous equations can be solved by plotting them on a graph but this can be time consuming. When solving simultaneous equations algebraically, the first step is to try to eliminate one of the ...

Abstract: It should not be surprising that in solving cubic equations, sooner or later you are going to have to take the cube root of something. But it's not immediately obvious what cubic equations ...

Abstract: For pt.2 see ibid., vol. 26, no. 4, p. 90-100 (2006). Our ultimate goal here is twofold. We want to get insight into how cubic polynomials work, what are the invariants/covariants and their ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...
