Looking forward, students can then progress to additional solving equations worksheets and other algebra worksheets, for example a sequences worksheet, simultaneous equations worksheet or straight line graphs worksheet.įor more teaching and learning support on Algebra our GCSE maths lessons provide step by step support for all GCSE maths concepts. the term 4x^2 has a coefficient of 4, or the coefficient of x^2 is 4. The coefficient of a term is the number in front of the power of x e.g. It is a second lesson after students have already had an introduction to solving quadratic equations by factorising, All quadratics in this lesson can be solved by factorising - they just must be re-arranged to give a quadratic equal to 0. Solving quadratics is a skill that is used extensively in A Level maths and so any student wanting to progress to A Level should ensure they are confident with these three methods. Quadratic equations usually have two solutions and when solving by completing the square, you must remember to include the positive and negative options when performing the square root to give both solutions. When solving by completing the square, any terms in x^2 and x must be on the left-hand side of the equation. When factorising quadratics or using the formula, it is important to ensure that all terms of the equation are on the left-hand side of the equation, with the right hand side being equal to zero. There are three methods that can be used to solve quadratic equations: factorising, using the quadratic formula or completing the square. The first questions have positive coefficients and a coefficient of 1 for the squared term. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: solve quadratic equations by factorisation solve quadratic equations by completing the square solve quadratic equations using a formula solve quadratic equations by drawing graphs Contents 1. Quadratic equations are equations where the highest power of x is 2. This solving equations worksheet requires students to solve 16 quadratic equations. exercises so that they become second nature.
