Answer 2

To simplify the given expression (3x - 4y) + 3a(b + y) + (x + y(x - y)), we can follow the order of operations (PEMDAS/BODMAS). This means simplifying any parentheses/brackets first, then exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right. Let's go step by step:

Step 1: Deal with the parentheses/brackets. (3x - 4y) + 3a(b + y) + (x + y(x - y))

1. Distribute the 3a into the (b + y) term: = 3x - 4y + 3ab + 3ay + (x + y(x - y))

2. Distribute the y into the (x - y) term: = 3x - 4y + 3ab + 3ay + (x + yx - y^2)

Step 2: Combine like terms. Combine the terms with 'y': = 3x - 4y + 3ab + 3ay + x + yx - y^2

Step 3: Group 'x' terms and 'y' terms together. = (3x + x) + (3ay - 4y) + 3ab + yx - y^2

Step 4: Combine like terms. = 4x + (3ay - 4y) + 3ab + yx - y^2

Step 5: Arrange the terms in standard form (highest power to lowest power). = 4x + yx + (3ay - 4y) + 3ab - y^2

So, the simplified expression is: 4x + yx + 3ay - 4y + 3ab - y^2
