Answer:
![(0.4x + 6y)^2](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%5E2)
Step-by-step explanation:
Given
![4.8xy+36y^2+0.16x^2](https://tex.z-dn.net/?f=4.8xy%2B36y%5E2%2B0.16x%5E2)
Required
Express as a binomial squared
![4.8xy+36y^2+0.16x^2](https://tex.z-dn.net/?f=4.8xy%2B36y%5E2%2B0.16x%5E2)
Rewrite as:
![0.16x^2+4.8xy+36y^2](https://tex.z-dn.net/?f=0.16x%5E2%2B4.8xy%2B36y%5E2)
Expand
![0.16x^2 + 2.4xy + 2.4xy + 36y^2](https://tex.z-dn.net/?f=0.16x%5E2%20%2B%202.4xy%20%2B%202.4xy%20%2B%2036y%5E2)
Factorize:
![0.4x(0.4x + 6y) + 6y(0.4x + 6y)](https://tex.z-dn.net/?f=0.4x%280.4x%20%2B%206y%29%20%2B%206y%280.4x%20%2B%206y%29)
Factor out 0.4x + 6y
![(0.4x + 6y)(0.4x + 6y)](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%280.4x%20%2B%206y%29)
Express as a square:
![(0.4x + 6y)^2](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%5E2)
Answer:
