multiply

(2-5b)(8+5b)

To multiply (2 - 5b)(8 + 5b), you can use the distributive property.

First, multiply 2 by 8:
2 * 8 = 16

Next, multiply 2 by 5b:
2 * 5b = 10b

Then, multiply -5b by 8:
-5b * 8 = -40b

Finally, multiply -5b by 5b:
-5b * 5b = -25b^2

Combining all the terms together, we have:

(2 - 5b)(8 + 5b) = 16 + 10b - 40b - 25b^2

Simplifying the equation further, we get:

16 - 30b - 25b^2
