  1. Finding zeros of polynomials (1 of 2) (video) | Khan Academy

    As you'll learn in the future, there's also going to be imaginary roots, or zeros, or there might be. Then we want to think about how many times, how many times we intercept the x-axis.

  2. Zeros of polynomials (with factoring): common factor

    When a polynomial is given in factored form, we can quickly find its zeros. When it's given in expanded form, we can factor it, and then find the zeros! Here is an example of a 3rd degree polynomial we …

    In the Practice Problems - Zeros of polynomials challenge problems, I can't figure out how to work any of those problems. Below is one example, all of the problems are similar.

  4. Zeros of polynomials & their graphs - Khan Academy

    Learn about the relationship between the zeros, roots, and x-intercepts of polynomials. Learn about zeros multiplicities.

  5. Zeros of polynomials (with factoring) (practice) | Khan Academy

    Use various methods in order to find all the zeros of polynomial expressions or functions.

  6. Zeros of polynomials (with factoring): grouping - Khan Academy

    When a polynomial is given in factored form, we can quickly find its zeros. When its given in expanded form, we can factor it, and then find the zeros! Here is an example of a 3rd degree polynomial we …

  7. Finding zeros of polynomials (2 of 2) (video) | Khan Academy

    If you don't, then you might wanna review your factoring polynomials. But if you have x plus a times x plus b, that's going to be equal to, x is going to be equal to x squared plus the sum of those two …

  8. Zeros of polynomials introduction (video) | Khan Academy

    The zeros of a polynomial p (x) are all the x-values that make the polynomial equal to zero. They are interesting to us for many reasons, one of which is that they tell us about the x-intercepts of the …

  9. Zeros of polynomials & their graphs (video) | Khan Academy

    Use the real 0's of the polynomial function y equal to x to the third plus 3x squared plus x plus 3 to determine which of the following could be its graph. So there's several ways of trying to approach it.
