b) = -3(2x²+12x-x-6) = -6x²-33x+18
c) = -(2y²+4y-2y-4) = -2y²-2y+4
d) = 2a²-(2a²-a+12a-6) = -11a+6
e) = 3x²-3-(x²-x-6) = 2x²+x+3
b) -3(2x-1)(x+6) = -3(2x²+12x-x-6) = -6x²-33x+18
c) -(y-1)(2y+4) = -(2y²+4y-2y-4) = -2y²-2y+4
d) 2a² - (a+6)(2a-1) = 2a²-(2a²-a+12a-6) = -11a+6
e) 3(x²-1) - (x-3)(x+2) = 3x²-3-(x²-x-6) = 2x²+x+3
