While factoring may not always be successful the Quadratic Formula can always find the solution. Quadratic Formula H A collection of 9-1 Maths GCSE Sample and Specimen questions from AQA OCR Pearson-Edexcel and WJEC Eduqas. First we bring the equation to the form ax²bxc0 where a b and c are coefficients.
Which factorises into x 3 x 2 a 2 3a.
See examples of using the formula to solve a variety of equations. To learn more about the student authors visit. The degree of the equation 2 the exponent on x makes the equation quadratic. 3 times 4 12 and 3 4 7 so a and b are equal to 3 and 4.
