Given that a polynomial function P(x) has rational coefficients.
Two roots are already given which are i and 7+8i,
Now we have to find two additional roots of P(x)=0
Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.
conjugate of a+bi is given by a-bi
So using that logic, conjugate of i is i
also conjugate of 7+8i is 7-8i
Hence final answer for the remaining roots are (-i) and (7-8i).

Answer:
Sir did you get the answer yet i may need help pls with um the 1.5 , area question and the 1.5 perimeter please?
Step-by-step explanation:
The equation used for this problem is
F = P(1+i)ⁿ
where
F is the future worth
P is the present worth
i is the effective interest rate
n is the number of years
Substituting the values,
F = <span>$8,000(1 + 0.03)</span>⁴
F = $9,004.07
Thus, after 4 years, Aaron will have $9,004.07.
