Answer:
5,
and ![-i\sqrt 6](https://tex.z-dn.net/?f=-i%5Csqrt%206)
Step-by-step explanation:
We are given that the polynomial
![f(x)=x^3-5x^2+6x-30](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3-5x%5E2%2B6x-30)
We have to find the all the zeroes of the polynomial function.
![f(x)=0](https://tex.z-dn.net/?f=f%28x%29%3D0)
![x^3-5x^2+6x-30=0](https://tex.z-dn.net/?f=x%5E3-5x%5E2%2B6x-30%3D0)
![x^2(x-5)+6(x-5)=0](https://tex.z-dn.net/?f=x%5E2%28x-5%29%2B6%28x-5%29%3D0)
![(x-5)(x^2+6)=0](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2%2B6%29%3D0)
![x-5=0](https://tex.z-dn.net/?f=x-5%3D0)
![x=5](https://tex.z-dn.net/?f=x%3D5)
![x^2+6=0](https://tex.z-dn.net/?f=x%5E2%2B6%3D0)
![x^2=-6](https://tex.z-dn.net/?f=x%5E2%3D-6)
![x=\pm\sqrt{-6}=\pm i\sqrt6](https://tex.z-dn.net/?f=x%3D%5Cpm%5Csqrt%7B-6%7D%3D%5Cpm%20i%5Csqrt6)
Using ![\sqrt{-1}=i](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D%3Di)
Hence, all the zeroes of the polynomial function are
5,
and ![-i\sqrt 6](https://tex.z-dn.net/?f=-i%5Csqrt%206)
