Finding real roots of polynomial equations

WebPut 0, if it doesn't work, put 1. You can also solve for the derivative polynomial to get the variations of the cubic. If there is only 1 root, 0 will do, if there are 3, start with any number between the roots of the derivative polynomial. – Alexandre C. Feb 6, 2011 at 8:51. 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.
