Answer 2

To simplify the expression (x-1):(1+1)(y²-x):(y+x), let's break it down step by step:

1. First, simplify (1+1) to 2: (x-1):2(y²-x):(y+x)

2. Next, distribute the 2 to both terms in the denominator: (x-1)/(2(y²-x))/(y+x)

3. To simplify further, let's factor out a negative sign from the denominator: (x-1)/(-2(x-y²))/(y+x)

4. Rearrange the terms in the denominator: (x-1)/(-2(-(y²-x)))/(y+x)

5. Simplify the double negatives: (x-1)/(-2(y²-x))/(y+x)

6. To simplify the negative signs, divide both the numerator and denominator by -1: -(x-1)/(2(y²-x))/(y+x)

7. Now, let's simplify the expression within the denominator: -(x-1)/(2y²-2x)/(y+x)

8. Divide the numerator by the denominator: -(x-1) * (y+x) / (2y²-2x)

9. Expand the numerator: -xy - x² + y - x / (2y²-2x)

So, the simplified expression is -(xy + x² - y - x) / (2y² - 2x).
