Finding the zeros of polynomial functions
WebThe number of zeros of a polynomial function is equal to the degree of the polynomial. Zeros of a Function Formula To find the zeros of a function f (x), we solve the equation f (x) = 0 for x. To find the roots of a function, we can use different methods to factorize the function and then equate it to 0. WebJul 12, 2024 · When finding the zeros of polynomials, at some point you’re faced with the problem x2 = − 1. While there are clearly no real numbers that are solutions to this equation, leaving things there has a certain feel of incompleteness. To address that, we will need utilize the imaginary unit, i. Definition: Imaginary number i
