👉 In mathematics, a Heron's formula is a form of quadratic formula used to solve equations of quadratic polynomials. It is named after the Italian mathematician Girolamo Cardano, who published it in his book Ars Magna (1545). The formula has many applications and can be generalized to higher dimensions. Heron's formula states that for any quadratic polynomial \(p(x)\) with real coefficients: \[ p(x) = x^2 + 2ax + b \
