To simplify the expression \((-8b)(-15b)\), you can follow these steps:

  1. Multiply the coefficients: \(-8 \times -15 = 120\) (since the product of two negative numbers is positive).

  2. Multiply the variable parts: \(b \times b = b^2\).

Putting it all together, we get: \[ (-8b)(-15b) = 120b^2 \]

Thus, the simplified expression is \(120b^2\).

So, the answer is: 120b².
