A polynomial has one root that equals 5 - 7i. Name one other root of this polynomial.Answer hereSUBMITarrow_backPREVIOUS
Question
Solution 1
The other root of this polynomial is 5 + 7i. This is because complex roots always come in conjugate pairs when the coefficients of the polynomial are real numbers. The conjugate of a complex number is found by changing the sign of its imaginary part. So, the conjugate of 5 - 7i is 5 + 7i.
