<h2>-2+5i and 2+5i</h2>
Step-by-step explanation:
Let the complex numbers be
.
Given, sum is
, difference is
and product is
.
⇒ ![a+c=0,b+d=10](https://tex.z-dn.net/?f=a%2Bc%3D0%2Cb%2Bd%3D10)
⇒ ![a-c=-4,b-d=0](https://tex.z-dn.net/?f=a-c%3D-4%2Cb-d%3D0)
![a=-2,c=2,b=5,d=5](https://tex.z-dn.net/?f=a%3D-2%2Cc%3D2%2Cb%3D5%2Cd%3D5)
![(a+ib)(c+id)=(-2+5i)(2+5i)=-4-25=-29](https://tex.z-dn.net/?f=%28a%2Bib%29%28c%2Bid%29%3D%28-2%2B5i%29%282%2B5i%29%3D-4-25%3D-29)
Hence, all three equations are consistent yielding the complex numbers
.
