👉 Learn how to simplify identities by factoring. Just like in normal algebraic expressions, trigonometric identities can be simplified by factoring out the GCFs from the terms of the identities, then common trigonometric identities like...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

In this video, students will learn how to find the volume of a rectangular prism by using their knowledge of geometric solids. The video explains the concepts of length, width, and height, as well as the difference between...

Shapes are all around song!

This is a song about different shapes for kids and toddlers. Children will love watching this shape video and singing along. It is a good video to teach children the different names of shapes. It is a...

Learn how to add/subtract rational expressions. When adding or subtracting two or more rational expressions with common denominators, we add or subtract only the numerator while we keep the denominator the same. We will then simplify our...

In this video, the teacher explains how to identify true statements about quadrilaterals, using examples of trapezoids, parallelograms, rhombuses, and squares. The teacher walks through each answer choice and eliminates incorrect...

In This Episode, Tyler Teaches Us About Properties of Special Parallelograms - Geometry

👉Learn how to factor quadratics using the difference of two squares method. When a quadratic contains two terms where each of the terms can be expressed as the square of a number and the sign between the two terms is the minus sign, then...

👉 Learn how to factor polynomials. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To factor an algebraic expression means to break it up...

In this lesson, students will learn how to model exponential decay using a table of values and function notation. They will understand the difference between linear functions and exponential decay functions, and how the decay factor...

👉Learn how to solve a quadratic equation by factoring out the GCF. When factoring out the GCF from an equation we will be looking for what the terms have in common. This method is very useful for quadratic equations that does not have...

In this video we discover what the difference of two squares means and how to factorise these ‘special’ quadratics.



To factorise these quadratics, you need to know the square numbers. Any expression that has x-squared as the...

In this video, the teacher explains how to identify an exponential relationship by looking for patterns in a problem. They emphasize that just because an exponent is used does not mean the relationship is exponential. The teacher...

In this video, students will learn how to find the area of a rectangle by multiplying the length by the width. The concept of area being the number of square units needed to cover a region is explained, and the misconception of adding...

In this video, the teacher explains how to find the zeros of a quadratic function by factoring a difference of perfect squares. They demonstrate the process using examples and emphasize the importance of factoring correctly. The teacher...

This video emphasizes the importance of multiplying the length and width to find the area of a rectangle, rather than mistakenly multiplying two sides of a parallelogram. The lesson also highlights the need for the height to be...

Definitions are very important to your understanding of why and how we use mathematical processes. Without understanding what a process or certain terms mean it is very hard to understand how or why to do something. That is why I want to...

👉 Learn how to write the equation of a polynomial when given imaginary zeros. Recall that a polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The...

Learn about the Pythagorean theorem. The Pythagoras theorem is a fundamental relation among the three sides of a right triangle. It is used to determine the missing length of a right triangle. The Pythagoras theorem states that the...
