Quadratic Equation. Here we will learn about the quadratic equation and how to solve quadratic equations using four methods: factorisation, using the quadratic equation formula, completing the square and using a graph. There are also quadratic equation worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
Whether you're revising for an exam or just need extra practice, this page has everything you need to build confidence in solving quadratic equations. Solving Quadratic Equations by Factorising. Usually the easiest and fastest method to solve a quadratic is by factorising. If we can write a quadratic as the product of two brackets, then we can ...
Solving equations GCSE questions. 1. Solve: 4y = 36. Show answer. y = 9 (1 mark) 2. Solve: x 2 − 5x − 24 = 0. Show answer. x = − 3, x = 8 (3 marks) 3. Solve: 7y − 8 = 13. ... Solve quadratic equations algebraically by using the quadratic formula (H) Solve quadratic equations by finding approximate solutions using a graph;
Solving Quadratics by Factorising How do I solve a quadratic equation using factorisation? Rearrange it into the form ax 2 + bx + c = 0. Zero must be on one side. It is easier if you rearrange so that a is positive. Factorise the quadratic and solve each bracket equal to zero. If (x + 4)(x - 1) = 0, then either x + 4 = 0 or x - 1 = 0Because if two things multiply together to give zero,
What is solving quadratic equations by factorising? Solving quadratic equations by factorising allows us to calculate values of the unknown variable in a quadratic equation using factorisation. To do this we make sure the equation is equal to 0, factorise it into brackets and then solve the resulting linear equations. E.g. Solve the following ...

GCE Maths revision section looking at Quadratic Equations. After studying this section, you will be able to: solve quadratic equations by factorising, solve quadratic equations by completing the square, solve quadratic equations by using the formula and solve simultaneous equations when one of them is quadratic.
Quadratic Equations Understanding Quadratic Equations. A quadratic equation is an equation that can be written in the standard form ( ax^2 + bx + c = 0 ), where ‘a’, ‘b’, and ‘c’ are constants, ‘x’ is the variable, and ( a ≠ 0 ).; The highest power of the variable in a quadratic equation is two.So if an equation involves a variable squared but not cubed, it is likely to be a ...
Quadratic equations represent parabolic graphs which have a shape of a U or an inverted U. Solving Quadratic Equations. Quadratic equations are solved by factoring, by using the quadratic formula, completing the square or by graphing. The factoring method involves expressing the equation in the form (px + q)(rx + s) = 0 and setting each factor ...
Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with GCSE Bitesize AQA Maths.
Solving quadratic equations is a fundamental concept in GCSE Maths, involving finding the roots or solutions of an equation in the form of ax² + bx + c = 0. The solutions can be found by factoring, completing the square, or using the quadratic formula. In this chapter we will investigate how we solve quadratic equations by factorising.
