Product of roots of a quadratic equation
WebbQuadratic Formula: The roots of a quadratic equation ax 2 + bx + c = 0 are given by x = [-b ± √(b 2 - 4ac)]/2a. This formula is also known as the Sridharacharya formula . Example: Let us find the roots of the same equation that was mentioned in the earlier section x 2 - 3x - 4 = 0 using the quadratic formula. Webb1 maj 2015 · 6. The reason the sum and product are great, but the difference and quotient are less great, is that the sum and product only depend on the (multi)set of roots, whereas in order to describe the difference and the quotient you need to pick a "first" root and a "second" root; that is, you need to break the (Galois) symmetry between the roots.
