-3x^2+13x-6

Explanation:

Simplify the 2(4x+6). This is equal to 8x+12. Now the equation is 8x+12-(3x^2-5x+18). Now distribute the negative in front of the -(3x^2-5x+18). Now the equation is (-3x^2+5x-18). The final equation is 8x+12-3x^2+5x-18. Combine 8x and 5x to get 13x. Then combine 12 and -18 to get -6. There is nothing to combine -3x^2 with so that is left alone. The final equation is -3x^2+13x-6.
