Answer:
Integer 1 is x
Integer 2 is y
x + y = -31
x - y = -55
Add:
2x = -86
x = -43
Substitute:
-43 + y = -31
y = 12
Therefore, the two integers are: 12 and -43

False
Step-by-step explanation:
<u>According to the complex conjugate root theorem:</u>
if a complex number is a root of a polynomial, its conjugate is also the root of the polynomial
We are given all the roots of the polynomial and there is only one complex root
Since according to the complex conjugate root theorem, there can be either none or at least 2 complex roots of a polynomial
We can say that this set of roots of a polynomial is incorrect
The answer is 2.625$ rounded up to 2.63$
