Answer:
x - 2y(x - 2y + 4)
Step-by-step explanation:
Given : (x - 2y)² + 4x - 8y
On solving further, we get
→ (x - 2y)² + 4(x - 2y)
→ (x - 2y)(x - 2y) + 4(x - 2y)
→ x - 2y(x - 2y + 4)

Step-by-step explanation:
HII
x^2-y^2-2y-1
x^2-(y^2+2y+1)
=x^2-(y^2+2•y• 1+1^2)
=x^2-(y+1)^2
=[x+(y+1)][x-(y+1)]
=[x+y +1][x-y-1]
