Find the product of −2+5i and its conjugate. The answer is a+bi where

29

Step-by-step explanation:

The given complex number is -2+5i

We need to find the product of −2+5i and its conjugate.

The conjuagate of -2+5i is -2-5i

So, it will become,

We know that,

Here, a = -1 and b = 5i

So, the values of a+bi is equal to 29.

e2020 got it right

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
