**Solving a cubic formula or a 3rd degree polynomial equation**

For example, if our cubic equation is given to us as 4x^2 + x^3 + 1 = 0, we need to rewrite it in the proper order with the x^3 term first. So, our cubic equation is rewritten as x ^3 + 4 x ^2 + 1 how to find axis intercepts 2/09/2011 · You need to differentiate the equation and put that equal to 0 and solve for x i.e. where the gradient is equal to 0. 3xSQ - 4x - 5 = 0 Use quadratic equation and sub in answers into original equation to get y coordinates
