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
