Answer 2

To simplify the expression (1+3x)(9x²-3x+1)-27x³, you can follow these steps:

1. First, distribute the (1+3x) to each term in the second expression (9x²-3x+1):

(1+3x)(9x²-3x+1) = (1)(9x²) + (1)(-3x) + (1)(1) + (3x)(9x²) + (3x)(-3x) + (3x)(1)

2. Now, simplify each of these terms:

9x² - 3x + 1 + 27x³ - 9x² + 3x

3. Combine like terms:

(9x² - 9x²) + (-3x + 3x) + 1

4. The first and second terms cancel each other out, leaving you with just 1:

So, the simplified expression is 1.
