Answer 3

It seems like you want to calculate the square of the expression (6b - c)² in algebra for a 7th-grade level. To do this, you can use the formula for squaring a binomial, which is (a - b)² = a² - 2ab + b². In your case, a is 6b, and b is c. So, you can square (6b - c) as follows:

(6b - c)² = (6b)² - 2(6b)(c) + (c)²

Now, let's simplify this expression step by step:

1. (6b)² = 36b² (squaring the first term)
2. 2(6b)(c) = 12bc (multiplying the first and second terms by 2)
3. (c)² = c² (squaring the third term)

Now, we can put it all together:

(6b - c)² = 36b² - 12bc + c²

So, (6b - c)² is equal to 36b² - 12bc + c² in algebra for a 7th-grade level.
