Answer 2

To solve the expression -b(b-8)+(b-6)(b+6) when b = -1/8, we need to substitute the value of b into the expression and then perform the calculations step by step. Let's go through the solution:

Step 1: Substitute the value of b into the expression: -(-1/8)(-1/8 - 8) + (-1/8 - 6)(-1/8 + 6)

Step 2: Simplify the expressions within the parentheses: -(-1/8)(-65/8) + (-49/8)(47/8)

Step 3: Perform the multiplications: (-1/8)(65/8) + (-2353/64)

Step 4: Multiply the fractions: -65/64 - 2353/64

Step 5: Combine the fractions: (-65 - 2353)/64

Step 6: Calculate the numerator: -2418/64

Step 7: Simplify the fraction, if possible: -1209/32

So, the simplified value of the expression -b(b-8)+(b-6)(b+6) when b = -1/8 is -1209/32.
