quadratic equation examples Example Solve x 2 4x 6 25 0 Coefficients are a 1 b 4 c 6 25 Note that the Discriminant is negative b2 4ac 4 2 4 1 6 25 9 Use the Quadratic Formula x 4 9 2 9 3 i where i is the imaginary number 1
For example the roots of the equation x 2 3x 4 0 are x 1 and x 4 because each of them satisfies the equation i e At x 1 1 2 3 1 4 1 3 4 0 At x 4 4 2 3 4 4 16 12 4 0 There are various methods to find the roots of a quadratic equation X b b2 4ac 2a The sign of plus minus indicates there will be two solutions for x Learn in detail the quadratic formula here Examples of Quadratics Beneath are the illustrations of quadratic equations of the form ax bx c 0
