Answer and Step-by-step explanation:
The signs didn't really "swap". Instead, the whole function was divided by -1, or we could say the function was divided by -3. That would turn:
-18x² - 15x + 3 = 0
into
(-18 / -3)x² - (15 / -3)x + (3 / -3) = 0
6x² + 5x - 1 = 0
And that gives the "swapped signs".

Answer:
-12x + 4
Step-by-step explanation:
(6x - 8 - 2x) - (12x - 7) - (4x - 5)
The subtraction sign before the parenthesis is basically multiplying by -1, so the subtraction signs in the parenthesis have to change to addition. After that, you can remove the parenthesis.
6x - 8 - 2x - 12x + 7 - 4x + 5
Simplified = -12x + 4
