There are a few different ways to solve quadratics: factorising, using the quadratic formula or by completing the square. In this video we look at solving by factorising.
In this video we’re going to discover how to factorise quadratics that don’t have 1 as the coefficient of the x-squared term. These are called non-monic quadratics. We can do it by trial and error and just spotting the factors, but this takes a lot of trial an error. Luckily there is a different method we can use instead, which we will looks at in this video.
YouTube video that explains how to use prime factorization to find the highest common factor and lowest common multiple. It is very simple using the method described in the video.
This YouTube video describes what recurring decimals are, and how to write them as fractions.
This YouTube video can help to get deeper understanding on solving ratio and proportion problems.
This video describes about similar shapes. It can help easily to find size of a side and angles of similar figures.
Density of a solid for a regular shaped body. Definition, meaning and its simple calculation
Concept of density. This YouTube video will provide information about the concept of density. It’s great to use as an introduction to the topic or as a way to summarise the topic.
This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work.
This is a simple video which describes how indices problems are solved using simplified laws.
