Factorising cubic expressions is a fundamental skill in algebra that involves expressing a cubic polynomial as a product of simpler factors. A cubic expression is a polynomial of degree three, typically in the form of ax + bx + cx + d, where a, b, c, and d are real numbers and a 0.
Factorising cubic expressions is important for various reasons. It allows us to solve cubic equations more easily, simplify algebraic expressions, and gain insights into the behaviour of cubic functions. Historically, mathematicians have developed various methods for factorising cubic expressions, including the sum and product of roots theorem, Vieta’s formulas, and Cardano’s method.
