To simplify the expression, you need to combine like terms and perform the necessary calculations. Here's the step-by-step process:
Distribute the 3x to both terms inside the parentheses: 3x * 4 = 12x 3x * (-2x) = -6x^2
Combine the terms inside the parentheses: 12x - 6x^2
Combine like terms outside the parentheses: -6 - 2x + 4 = -2x - 2
Now, put it all together: 12x - 6x^2 - 2x - 2
To simplify further, you can combine the like terms: 12x - 6x^2 - 2x - 2 = (12x - 2x) - 6x^2 - 2 = 10x - 6x^2 - 2
So the simplified expression is 10x - 6x^2 - 2.
