Question

factorise x^2-y^2+2n+1​

Answer 1

Answer: I don't no

Step-by-step explanation:

Answer 2

Answer:It is actually very simple if you notice that the quadratic polynomial in y is the square of a linear one.

x2−y2−2y−1=x2−(y2+2y+1)

⟹x2−y2−2y−1=x2−(y+1)2

⟹x2−y2−2y−1=[x+(y+1)][x−(y+1)]

⟹x2−y2−2y−1=(x+y+1)(x−y−1)
