b. (x+3)(x-2) = x(x-2)+3(x-2) = x²-2x+3x-6 = x²+x-6
c. (2x-1)(x+2y-3) = 2x(x+2y-3) - 1(x+2y-3) = 2x²+4xy-6x-x-2y+3 = 2x²+4xy-7x+3

A.4(3a+2)=(4 x 3a)+(4 x 2)=12a+8 B.(x+3)(x-2)=x(x-2)+3(x-2)=x²-2x+3x-6=x²+x-6 C.(2x-1)(x+2y-3)=2x(x+2y-3)-1(x+2y-3)=2x²+4xy-6x-x-2y+3=2x²+4xy-6x-x-2y+3=2x²+4xy-7x-2y+3
b. (x+3)(x-2) = x(x-2)+3(x-2)
= x²-2x+3x-6
= x²+x-6
c. (2x-1)(x+2y-3) = 2x(x+2y-3) - 1(x+2y-3)
= 2x²+4xy-6x-x-2y+3
= 2x²+4xy-7x+3
B.(x+3)(x-2)=x(x-2)+3(x-2)=x²-2x+3x-6=x²+x-6
C.(2x-1)(x+2y-3)=2x(x+2y-3)-1(x+2y-3)=2x²+4xy-6x-x-2y+3=2x²+4xy-6x-x-2y+3=2x²+4xy-7x-2y+3
