Answer 2

This is a polynomial of degree 4, because you have 4 roots real or imaginary:1st) x= 5 →(x-5)=0

2nd) x = - 3→(x+3) =0

3rd) x = -1+3i →(x+1-3i) = 0

and the 4th one that is not mentioned which is the conjugate of 

-1+3i, that is -1-3i (in any polynomial if a root has the form of a+bi, there is always a conjugate root = a-bi)

 

4th) x= -1-3i→(x+1+3i) = 0

Hence the polynomial =(x-5)(x+3)((x+1-3i)(x+1+3i)

Solving the above will give you (unless I am mistaken, pls recalculate):

x⁴-9x²-50x-150
