Answer 2

To simplify the expression, let's expand and combine like terms:

3x(x + y + c) - 3y(x - y - c) - 3c(x + y - c)

Step 1: Distribute the constants in each bracket. 3x * x + 3x * y + 3x * c - 3y * x + 3y * y + 3y * c - 3c * x - 3c * y + 3c * c

Step 2: Combine like terms. Now, let's simplify it further: 3x^2 + 3xy + 3xc - 3xy + 3y^2 + 3yc - 3cx - 3cy + 3c^2

Step 3: Combine like terms again. 3x^2 + 3y^2 + 3c^2 + (3xy - 3xy) + (3xc - 3cx) + (3yc - 3cy)

Step 4: Simplify further. 3x^2 + 3y^2 + 3c^2 + 0 + 0 + 0

Step 5: Final result. The simplified expression is: 3x^2 + 3y^2 + 3c^2
