Question

(3y-3c) (2c-2y) help my!!!!!!

Answer 1

Если не ошибаюсь то 6yc-6y-6c+6cy

Answer 2

To simplify the expression (3y - 3c)(2c - 2y), you can use the distributive property of multiplication over addition/subtraction. Here's the step-by-step process:

1. Apply the distributive property: (3y - 3c)(2c - 2y) = 3y(2c - 2y) - 3c(2c - 2y)

2. Multiply the terms inside the parentheses: = 6yc - 6y^2 - 6c^2 + 6cy

3. Combine like terms: The terms -6y^2 and 6cy are like terms (both contain the variable y), so they can be combined: = -6y^2 + 6cy + 6yc - 6c^2

4. Rearrange the terms in descending order of the variable: = -6y^2 + (6cy + 6yc) - 6c^2

5. Simplify the middle terms: Since 6cy and 6yc are like terms (they both contain the variables c and y), they can be combined: = -6y^2 + 12cy - 6c^2

So, the simplified expression is -6y^2 + 12cy - 6c^2.
