Hence many online sites online provide quadratic equation calculator which are very easy to use. While a scientific calculator might be used to calculate the roots of a quadratic equation, it is always not a convenient method. Quadratic Equation CalculatorĪ quadratic equation calculator is a special calculator, which is used to solve the complex quadratic equations. Here we have provided you with a table showing the quadratic formula, so it will be easy for you to memorize and apply it. So you would obtain two roots, one in “+” and one in “-“, and both are the solutions to the equation. Any quadratic equation has two solutions or roots. Now if you require to solve the quadratic equation, you have to use the quadratic formula. Thanks to the SQA and authors for making the excellent resources below freely available.

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.
