Answer 2

It seems like there's a mix of mathematical expressions and some unusual characters in the expression you provided. Let's simplify the expression step by step:

5(3a + b) - 15a^2(a + 5b) + 6(0.5a - b)

First, let's distribute the constants and variables within the parentheses:

= 15a + 5b - 15a^3 - 75ab + 3a - 6b

Now, let's combine like terms:

= 15a + 3a - 15a^3 - 75ab + 5b - 6b

Combine the "a" terms:

= 18a - 15a^3 - 75ab

Combine the "b" terms:

= 18a - 15a^3 - 75ab - b

So, the simplified expression is:

18a - 15a^3 - 75ab - b
