The quadratic formula, x equal to minus b plus minus root over b square minus 4ac upon 2a, is essential for solving quadratic equations and is credited to the Indian mathematician Sridaracharaya, providing two solutions for x. Specifically, applying the quadratic formula to a quadratic equation with coefficients 2, 5, and -6 results in x equal to -5 plus minus root over 73 by 4, giving the two solutions for x.
Insights
