Step-by-step explanation:
Given

Required
Find U and V
We have:

Expand

Expand

Group
![[x^2 + 10x] + [10x + 100] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%5E2%20%2B%2010x%5D%20%2B%20%5B10x%20%2B%20100%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factorize each group
![x[x + 10] + 10[x + 10] = (U + V)^2](https://tex.z-dn.net/?f=x%5Bx%20%2B%2010%5D%20%2B%2010%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
Factor out x + 10
![[x + 10][x + 10] = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%20%2B%2010%5D%5Bx%20%2B%2010%5D%20%3D%20%28U%20%2B%20V%29%5E2)
So, we have:
![[x + 10]^2 = (U + V)^2](https://tex.z-dn.net/?f=%5Bx%20%2B%2010%5D%5E2%20%3D%20%28U%20%2B%20V%29%5E2)
