Zeros of a Cubic Polynomial - Sum, Product, Roots

The zeros of a cubic polynomial ax³ + bx² + cx + d are the three values of x that make it equal zero, always three when counted with multiplicity. This article derives the sum and product of those zeros from the coefficients, shows how to find them, explains the four possible root patterns, and works through six examples.

Types of Relations - Reflexive, Symmetric, Transitive

The main types of relations in math are empty, universal, identity, inverse, reflexive, symmetric, transitive, antisymmetric, and equivalence relations. This article defines each type, shows it with set examples written in … notation, explains how equivalence and antisymmetric relations differ, and works through six problems.

Sum of N Terms of an AP - Formula, Derivation, and Examples

The sum of n terms of an AP is Sₙ = n/2[2a+(n-1)d], where a is the first term, d the common difference, and n the number of terms. This article derives that formula by adding the series to its own reverse, then works through six examples, the natural-numbers special case, and the errors that trip students up.
