it's supposed to have the 2 under the b-6 can you show your work please thank you sorry for the mistake

No problem at all! I'm here to help. To show the work for the expression "b-6 with 2 underneath," it sounds like you are referring to "b-6" raised to the power of 2, or b-6 squared.

To calculate b-6 squared, we multiply the expression by itself. This can be represented as (b-6)(b-6). Using the distributive property, we can expand it as follows:

(b-6)(b-6) = b(b) + b(-6) + (-6)(b) + (-6)(-6)

Simplifying, we get:

b^2 - 6b - 6b + 36

Combining like terms, we have:

b^2 - 12b + 36

Therefore, the expression (b-6) raised to the power of 2, or (b-6)^2, simplifies to b^2 - 12b + 36.
