A polynomial function P(x) with rational coefficients has the given roots. Find two additional roots of P(x)=0.

i and 7 + 8i

a) -1,1

b) -i, 7-8i

c)-1, 56i

d) no additional roots are possible

Also if anyone has the answers to the practice and the quick check i’m super behind and I need help ASAP!!
