For further practice/worksheets please click on our N5 Maths website Quadratic Formula link HERE To find the roots, the quadratic equation is compared with ax² + bx + c to find the values of a, b & c.Ĭomparing the above equations: a = 1, b = 5, c = 7. These values are substituted into the quadratic formula to give two answers with decimals (roots of the equation). In exams, when asked to solve a quadratic correct to a number of decimal places, or significant figures, then the quadratic formula must be used. The reason that the trinomial does not factorise is because the solution to the equation (the roots) have a decimal value There are no combinations of numbers which multiply to give 7 and add to give 5 When would you use the Quadratic Formula? Inside the square root is the discriminant which is used to find the Nature of the Roots.Is NOT given in the Higher Maths Exam – please memorise.Is used to solve quadratic equations which do not factorise.Exam Focused Online Study Pack – For students looking for a ‘good’ Pass ![]() Higher Maths Past Paper Video SolutionsĢ1.
