Answer 2

It seems like you have a mathematical expression, but it's a bit unclear and appears to have some typographical errors. Let's try to understand and correct it.

The expression you provided is: 2x + 3X + 21)1 - x423

It seems like there might be a typo with the capital "X" and the placement of the closing parenthesis. I'll assume you meant to write it as:

(2x + 3x + 21) * (1 - x) * 423

In this corrected expression, I've added the missing asterisks (*) for multiplication, converted the uppercase "X" to lowercase "x," and adjusted the placement of parentheses for clarity.

If this is not what you intended, please provide more information or clarify your question, and I'd be happy to help further.
