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.

Designed for OL & HL students. (Video three is for HL students only)

Video one looks at how you can solve a linear equation by finding the value of x that makes the equation true.

Video two looks at how you can solve a quadratic equation by finding the values of x which satisfy the equation. After watching these videos, try to form the quadratic equation when given the two roots. Video three was designed for higher level Mathematics students and it demonstrates how you can form the quadratic equation when given the two roots.
