Learn about polynomial zeros and their multiplicities on Khan Academy.

2021年3月10日 · This is in regards to the Algebra II section Zeros of polynomials and their graphs. It might be worth expanding the the explanation of question #6 to point out that the multiplicity of y=x-6 is literally 1, and then derive or even just show the formula for the graph: f (x) = − (x+4)^2* (x−6)

Identify zeros of quadratic functions, and use the zeros to sketch a graph of the function defined by the polynomial.

Solve challenging problems that tackle the relationship between the features of a polynomial and its graph.

Identify zeros of polynomials when suitable factorizations are available. Use the zeros to construct a rough graph of the function defined by the polynomial.
