a^2+b^2

Step-by-step explanation:

We are given that (a+ib)(a-ib)

We are given that a and b are both not equal to zero

We have to find the product of (a+ib)(a-ib)

a(a-ib)+ib(a-ib)

a^2-iab+iba-i^2b^2

We know that i^2=-1

Substitute the value then we get

a^2-(-1)b^2

a^2+b^2

Hence, (a+ib)(a-ib)=a^2+b^2
