Description

A quadratic is a type of problem that deals with a variable multiplied by itself. This operation is known as squaring and is derived from the area of a square with its side length multiplied by itself. This course will teach you how to factorize quadratics. You will look at equations with linear functions in the denominator, quadratic equations with both brackets of the same sign, and quadratic equations with both brackets of different signs. You will also study quadratic equations using specific formulae.

Surds are numbers left in root form (√) to express their exact value. They are left as surds is because, in the decimal form, they would go on infinitely. This course will teach you how to simplify surds with a some simple rules. You will learn how to use discriminants for quadratic equations and how to solve linear inequalities with fractions. You will also study the different methods for solving quadratic inequalities, and more.
