Question

How can I create a quintic polynomial function with 1,3,4, and 5 real zero values? step by step pleaseee:)

Answer 1

@moneybird, she really did ask step-by-step? So why does your method work? And btw, isn't the polynomial you're written down 4th order, not 5th like the question asks?

Answer 2

pick 5 real zero values, such as 5,6,7,8,9, and make them zeros by multiplying: \[(x-5)(x-6)(x-7)(x-8)(x-9)\] Similarly pick for example 1 real value and 4 complex values in conjugate pairs and multiply:\[(x-5)(x+i)(x-i)(x+2i)(x-2i)\]to get only 1 real value...

Answer 3

thankkk yaaa:)

Answer 4

When you multiply a polynomial with zeros (like 5,6,7) times another polynomial with zeros (like 8,9), you get a new polynomial that has all of those zeros and no others.

alriight, let me try it
