the quadratic. [Edexcel GCSE Nov2015-2H Q22] Alison is using the quadratic formula to solve a quadratic equation. She substitutes values into the formula and correctly gets = −7±√49−32 4 Work out the quadratic equation that Alison is solving. Give your answer in the form 2+ + =0, where , and are integers.
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 ...

Tutorials, tips and advice on GCSE Maths coursework and exams for students, parents and teachers. Solving Quadratic Equations: Solving equations like ax² + c = 0 can be quite straightforward. e.g. x² - 25 = 0. From your work on algebra, you should be able to rearrange the equation to: x² = 25.
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,

Solve quadratic equations algebraically by using the quadratic formula (H) Solve quadratic equations by finding approximate solutions using a graph;
A quadratic equation is an equation whose power is in the second degree. In an equation, at least one of the variables is squared. In finding the missing value, it can be solved by factoring, completing the square and using the quadratic formula. Example: \( x^2\) + 2x +1 = 0 The first term \(x^2\) is in the second degree or second power. Solve ...
