In algebra, a conjugate is a binomial formed by negating the second term of a binomial. The conjugate of x + y is x − y, where x and y are real numbers. If y is imaginary, the process is termed complex conjugation: the complex conjugate<span> of a + bi is a − bi, where a and b are real
Therefore the binomial to be multiplied is its conjugate which would be:
