Solving higher order polynomial equations is an essential skill for anybody studying science and mathematics. However, understanding how to solve these kinds of equations is quite challenging.
This article will discuss how to solve the cubic equations using different methods such as the division method, Factor Theorem, and factoring by grouping.
But before getting into this topic, let’s discuss what a polynomial and cubic equation is.
A polynomial is an algebraic expression with one or more terms in which an addition or a subtraction sign separates a constant and a variable.
The general form of a polynomial is axn + bxn-1 + cxn-2 + …. + kx + l, where each variable has a constant accompanying it as its coefficient. The different types of polynomials include; binomials, trinomials and quadrinomial. Examples of polynomials are; 3x + 1, x2 + 5xy – ax – 2ay, 6x2 + 3x + 2x + 1 etc.
A cubic equation is an algebraic equation of third-degree.The general form ...
