Simplifying
12x^2 + -27
Reorder the terms:
-27 + 12x^2
Factor out the Greatest Common Factor (GCF), '3'.
3(-9 + 4x^2)
Factor a difference between two squares.
3((3 + 2x)(-3 + 2x))
Final result:
3(3 + 2x)(-3 + 2x)

You can take it one step further since 4x^2-9 factors into
(2x+3)(2x-3)

12x^2-27
= 3(4x ² -9)
= 3(2x-3)(2x+3)

3 (4x² - 9)
3(2x - 3)(2x + 3)

you go simplify more:
3(2x - 3)(2x + 3)
Anyway, well done :-)
