$- 3 x^{2} + 13 x - 6$ $-3x^2+13x-6$

Explanation:

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