Simplify the expression - 3 (x 3) 2 - 3 3x. what is the simplified expression in standard form? - 3x2 - 18x - 27 - 3x2 - 15x - 30 - 3x2 3x 6 - 3x2 3x - 30

Assuming that the spaces in between terms stand for the "+" symbol, then the expansion of the given expression is as follows:

-3 (x + 3) ^2 - 3 + 3x-3 (x^2 + 6x + 9) - 3 + 3x-3x^2 - 18x - 27 - 3 + 3x-3x^2 - 15x - 30

Therefore, the correct answer is the second choice: - 3x^2 - 15x - 30.
