WebThe Cardano's formula (named after Girolamo Cardano 1501-1576), which is similar to the perfect-square method to quadratic equations, is a standard way to find a real root of a cubic equation like. ax^3+bx^2+cx+d=0. ax3 +bx2 +cx+ d = 0. We can then find the other two roots (real or complex) by polynomial division and the quadratic formula.
Many different methods to derive the quadratic formula are available in the literature. The standard one is a simple application of the completing the square technique. Alternative methods are sometimes simpler than completing the square, and may offer interesting insight into other areas of mathematics.
