Answer 2

To evaluate the given expression for the values of a and b, which are a = 10 and b = -1, we can substitute these values into the expression and perform the calculations.

The expression is: 5x + 2ab^2 - 8ab^2

Now, substitute a = 10 and b = -1 into the expression:

5x + 2(10)(-1)^2 - 8(10)(-1)^2

Since (-1)^2 = 1, we get:

5x + 2(10)(1) - 8(10)(1)

Now, perform the calculations:

5x + 20 - 8(10)

5x + 20 - 80

5x - 60

So, the simplified expression for the given values of a and b (a = 10 and b = -1) is 5x - 60.
