Graph and determine the number of zeros
WebMar 8, 2024 · The fundamental theorem of algebra states there are the same number of total zeros as the degree of the polynomial so there will be 5 total zeros. Descartes Rule … Webx − 5 = 0 ⇒ x = 5. The multiplicity of each zero is the number of times that its corresponding factor appears. In other words, the multiplicities are the powers. (For the factor x − 5, the understood power is 1 .) Then my answer is: x = −5 with multiplicity 3. x = −2 with multiplicity 4. x = 1 with multiplicity 2.

It is not saying that the roots = 0. A root or a zero of a polynomial are the value (s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0. 2 comments. failing liver medicationIn mathematics, the zeros of real numbers, complex numbers, or generally vector functions f are members x of the domain of ‘f’, so that f (x) disappears at x.
