# Inequalities

UCD Maths Support Centre in conjunction with the UCD Access Support Centre created the following collection of resources for Leaving Certificate Mathematics students. The videos and accompanying PDF were designed for both the Higher and Ordinary Level Mathematics course.

This collection focuses on the Leaving Certificate Mathematics Strand 4: Algebra.

## Inequalities

Designed for OL   &   HL students.
Learn some of the rules we use when working on inequalities. The instructor in the videos will demonstrate how you can solve some inequality questions and how you can illustrate the solution on a number line.

## Inequalities with Quadratics & Algebraic Fractions

Designed for HL students only.
Learn how to solve inequalities with quadratics by finding where the quadratic cuts the x-axis or learn how solve questions involving inequalities with algebraic fractions. These videos highlight the important steps and common errors made by students when solving inequalities.

## Absolute Value

Designed for HL students only.
The absolute vale |x| of a number is its magnitude without regard to its sign.
Can you solve inequality problems involving absolute value? These videos will demonstrate how you can.
