WebThe multiplicity of a zero or a root is the number of times its related factor appears in the polynomial. For example, a quadratic equation (x+5)(x-3) has the root x= -5 and x = 3. ... Webthe root λ 0 = 2 has multiplicity 1, and the root λ 0 = 1 has multiplicity 2. Definition. Let A be an n × n matrix, and let λ be an eigenvalue of A. The algebraic multiplicity of λ is its multiplicity as a root of the characteristic polynomial of A. The geometric multiplicity of λ is the dimension of the λ-eigenspace.

WebA polynomial function can have 0 zeros, 1 zero, or many zeros. Positive, odd-order polynomial functions must have at least one zero, but positive, even-order polynomial functions may or may not contain a zero. Any polynomial of positive order, whether odd or even, can have a maximum number of zeros equal to its order. Also Read: WebWe can set this function equal to zero and factor it to find the roots, which will help us to graph it: f (x) = 0 x4 + 5x2 + 4 = 0 (x2 + 1) (x2 + 4) = 0 (x + i) (x – i) (x + 2i) (x – 2i) = 0 So the roots are x = i, -i, 2i, and -2i. This means that the graph has no real roots, so it never touches the x-axis. tweezerman brow scissors

Can a root have a multiplicity of zero

http://www.math.lsa.umich.edu/~kesmith/217Dec4.pdf WebSince (x+1) is squared, it has multiplicity 2, which means there's two of them in the factor list. This results in the line of the graph just barely touching zero, rather than crossing it. So you're looking for a graph with zeros at x=-1 and x=2, crossing zero only at x=2.
