WebYou 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. You want to do that because p ( x) will be a polynomial of degree 2 and it is easy (see here ) to find the solutions of such polynomial. In your case you have (with Horner's method) WebTake the equation 10x^3-10x^2-32, for example. The degree of the function is the highest degree, and the degree of the first term when put in standard form. The Fundamental Theorem of Algebra ultimately says that the degree of the polynomial, n, is how many roots the polynomial will have as long as you are counting complex numbers (which we are).
