Answer 2

y(4x-y)+(x-y)²-x²=4xy-y²+x²-2xy+y²-x²=2xy

((A-B)²=A²-2AB+B²)

Answer 3

Let's simplify the given expression step by step:

1. Start with the expression: Y(4x-y) + (x-y)^2 - x^2

2. Expand the square term (x-y)^2: (x-y)^2 = (x-y)(x-y) = x^2 - 2xy + y^2

3. Substitute the expanded square term back into the expression: Y(4x-y) + (x^2 - 2xy + y^2) - x^2

4. Now, combine like terms: Y(4x - y) + x^2 - 2xy + y^2 - x^2

5. The x^2 and -x^2 cancel each other out: Y(4x - y) - 2xy + y^2

So, the simplified expression is: Y(4x - y) - 2xy + y^2
