The product of the complex number (−6 −3i) and its conjugate is; 45.
It follows from the task content that the complex number in discuss can be multiplied with its Conjugate as follows;
(−6 −3i) (−6 +3i)
Hence it follows from the converse of the difference of two squares theorem that;
(−6 −3i) (−6 +3i) = (−6)² −(3i)²
= 36 - 9i²
= 36 -9(-1)
= 36+9
= 45.
