Question

How do you Factorise x²+y²

Answer 1

Step-by-step explanation:

The difference of squares, x² – y², can be factored as the product of the sum and difference of two terms, or x² – y² = (x + y)(x – y). Example: 2x2 – 18 = 2(x² – 9), = 2(x – 3)(x + 3).

Answer 2

Step-by-step explanation:

(x+y)²-2xy

x²+y²+2xy-2xy
