Question

How to prove conjugate pair is a rational number ​

Answer 1

Step-by-step explanation:

Mathwords: Conjugate Pair Theorem. An assertion about the complex zeros of any polynomial which has real numbers as coefficients. has real coefficients, then any complex zeros occur in conjugate pairs. That is, if a + bi is a zero then so is a – bi and vice-versa.

You find the complex conjugate simply by changing the sign of the imaginary part of the complex number. To find the complex conjugate of 4+7i we change the sign of the imaginary part. Thus the complex conjugate of 4+7i is 4 - 7i. To find the complex conjugate of 1-3i we change the sign of the imaginary part.
