Quadratic equations have expression in the power of 2s or squares. Solving quadratic equations involves collecting of like terms, simplification and substitution. The videos explain the processes involved in solving quadratic equations, with examples.
2.Simultaneous Linear and Quadratic Equations
This involves solving algebraic equations with two or more different algebraic terms. Expressions like 2x+4y have terms in x and y. The videos explain, with examples, how to solve such mathematical problems.
3.Linear Inequalities
Solving equations in which the terms are not exactly equal to each other, certain much be adhered to. The video below explain linear inequalities extensively
4.Gradients of Straight lines and Curves
The gradient of a straight line is a measure of how steep it is. The gradient of a straight line is constant at any point on the line. The gradient of a curve at any point is the gradient of the tangent at that point. The video shows the processes involved in finding gradients.
5.Algebraic Fractions
In algebra, an algebraic fraction is a fraction is a fraction whose numerator and denominator are algebraic expressions. The video gives different ways algebraic fractions can be put in math questions and how they can be solved.
