find all zeros of the function.

f(x) = x^3-10x^2+33x-34

I found 2, using my calculator. What do i do after that?

  1. One you have one zero, say x = 5.3 (invented example number)
    Then divide the original polynomial by (x-5.3)
    That leaves you with a quadratic, which you can solve with your calculator.

  3. Use the quadratic equation
    if
    y = a x^2 + b x + c
    then y is zero if
    x = -b/2a +or- (1/2a)sqrt(b^2 - 4 a c)
