Someone please help...How do I form a polynomial f(x) with real coefficients having a degree of 4 and zeros -5 - 5i, -5 with a multiplicity of 2?

Question

Can you form a polynomial with real coefficients having zeros 3 and 1?

ddcamp · Answer

If a function has the zeroes a, b, and c, we know that the function is:
(x-a)(x-b)(x-c)
expanded.

If one of the zeroes has multiplicity 2, it shows up twice:
(x-a)(x-b)(x-c)(x-c)
