The general quadratic equation ax² + bx + c = 0. has roots This formula, known as the quadratic formula, is actually two formulas. The ± symbol should be read as plus or minus, which means that you have to work out the formula twice, once with a plus sign in that. A number of Indian mathematicians gave rules equivalent to the quadratic formula. It is possible that certain altar constructions dating from ca. 500 BC represent solutions of the equation, but even should this be the case, there is no record of the method of solution (Smith 1953, p. 444). The Hindu mathematician Āryabhata (475 or 476-550) gave a rule for the sum of a geometric series that.

The Quadratic Formula. At the end of the last section (Completing the Square), we derived a general formula for solving quadratic equations. Here is that general formula: For any quadratic equation ax^2+ bx + c = 0, the solutions for x can be found by using the quadratic formula: x=(-b+-sqrt(b^2-4ac))/(2a) The expression under the square root, b^2− 4ac, can tell us how many roots we'll. Quadratic formula definition is - a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ± √(b2 — 4ac))/(2a) This formula lets you solve quadratic equations, which by some are considered to be one of the difficult aspects of algebra. Some consider it to be a gibberish concatenation of as, bs and cs along with some coefficients. Yet it is crucial to the very existence of algebra and its related subroutines.
