Overview

A quadratic equation is an equation formed from a quadratic polynomial and written in standard form as ax^2 + bx + c = 0, where x is the variable and a, b, c are constants. A quadratic polynomial becomes a quadratic equation when it is equated to zero. The chapter focuses on identifying quadratic eq

Key Concepts

A polynomial of degree two

A polynomial of degree two is called a quadratic polynomial. It becomes a quadratic equation when it is equated to zero.

A quadratic polynomial equated to zero

A quadratic polynomial equated to zero is called a quadratic equation. It is studied in one variable and usually written in standard form.

The standard form is ax^2 +

The standard form is ax^2 + bx + c = 0. Every quadratic equation can always be written in this form.

The value of the variable

The value of the variable for which the left-hand side and right-hand side of the equation become equal is called a root or solution.

A quadratic equation is factorised into

A quadratic equation is factorised into linear factors, and each factor is set equal to zero to find the roots.

Learning Objectives

  • Identify a quadratic equation from a given set of equations
  • Write quadratic equations in standard form
  • Solve quadratic equations by factor method
  • Solve quadratic equations using the quadratic formula
  • Use the discriminant to find the nature of roots
