Help your students prepare for their Maths GCSE with this free inequalities worksheet of 30+ questions and answers
Inequalities demonstrate relationships between two expressions that are not equal to each other. There are four types of inequalities: greater than >, less than <, greater than or equal to ≥ and less than or equal to ≤. For example, x>4 means x is greater than 4 , so x could be 5, 6, 7, … etc.
Single variable inequalities can be represented on a number line and we can also list the integer (whole number) solutions to inequalities.
Solving algebraic inequalities such as linear inequalities and quadratic inequalities is very similar to solving algebraic equations, but instead of using an equals sign we use an inequality symbol. As with linear equations, we can have one step inequalities, two step inequalities and unknowns on each side of the inequality. The solution to an inequality represents a range of values rather than one number.
Quadratic inequalities are initially dealt with in the same way as quadratic equations by calculating the roots of the equation by factorising or using the quadratic formula. These roots can then be plotted and the general graph can be sketched. The possible values for x can then be worked out by looking for the values of x where the graph is either above or below the x axis.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
