Answer 3

To simplify the expression (b-6)b-(5-b)^2, we'll follow the order of operations (PEMDAS/BODMAS):

1. Simplify the expression inside the parentheses (5-b)^2.
2. Perform any necessary operations within the parentheses.
3. Continue with the multiplication and subtraction.

Let's go step by step:

1. Simplify (5-b)^2: (5-b)^2 = (5-b)(5-b) = 25 - 5b - 5b + b^2 = 25 - 10b + b^2

2. Now we have (b-6)b - (10b - 25): Distribute the b into (b-6): b * b = b^2 b * (-6) = -6b

   So, the expression becomes: b^2 - 6b - (10b - 25)

3. Distribute the negative sign into the parentheses:

   • (10b - 25) = -10b + 25

Now the expression is: b^2 - 6b - 10b + 25

4. Combine like terms: -6b and -10b are like terms, so their coefficients can be added together: b^2 - 6b - 10b + 25 = b^2 - 16b + 25

So, the simplified expression is b^2 - 16b + 25.
