How to Find the Roots of a Polynomial Sciencing

WebYou would put the absolute value of the result on the z-axis; when x is real (complex part is 0) the absolute value is equal to the value of the polynomial at that point. The absolute value is always non-negative, and the solutions to the polynomial are located at the points where the absolute value of the result is 0. WebFor polynomial of degree 3 you can use the following procedure. Assume that you guessed the solution x 1 = 4 (indeed 4 3 − 6 ⋅ 4 2 − 2 ⋅ 4 + 40 = 64 − 96 − 8 + 40 = 0). You can use Horner's method to get the polynomial p ( x) = p 2 x 2 + p 1 x + p 0 such that ( x − 4) ⋅ p ( x) = x 3 − 6 x 2 − 2 x + 40. WebThe typical approach of solving a quadratic equation is to solve for the roots x = − b ± b 2 − 4 a c 2 a Here, the degree of x is given to be 2 However, I was wondering on how to solve an equation if the degree of x is given to be n.
