a² + 2ab + b² = (a+b)²
16x² + 40xy + 25y²
= (4x)² + 2(4x)(5y) + (5y)²
= (4x+5y)²

16x^2 + 40xy + 25y^2 = 16x^2 + 20xy + 20xy + 25y^2
16x^2 + 40xy + 25y^2 = 4x(4x + 5y) + 5y(4x + 5y)
16x^2 + 40xy + 25y^2 = (4x + 5y)(4x + 5y)
16x^2 + 40xy + 25y^2 = (4x + 5y)^2

16x^2 + 40xy + 25y^2
16x^2 + 20xy + 20xy + 25y^2
4x(4x + 5y) + 5y(4x + 5y)
(4x + 5y)^2

16x^2 + 40xy + 25y^2
= 16x^2 + 20xy + 20xy + 25y^2
= 4x(4x + 5y) + 5y(4x + 5y)
= (4x + 5y)(4x + 5y)
