a)W(x)+P(x)
3x³-4x²+5x-6+2x³-7x+3=5x³-4x²-2x-3
b)W(x)+Q(x)
3x³-4x²+5x-6+ 4x²-3x+2= 3x³+2x-4
c)W(x)-Q(x)
3x³-4x²+5x-6- (4x²-3x+2)= 3x³-4x²+5x-6-4x²+3x-2=3x³-8x²+8x-8
d)W(x)-P(x)
3x³-4x²+5x-6- (2x³-7x+3)= 3x³-4x²+5x-6-2x³+7x-3=x³-4x²12x-9
e)Q(x)-P(x)
4x²-3x+2- (2x³-7x+3)= 4x²-3x+2- 2x³+7x-3= -2x³+4x²+4x-1
g)-Q(X)+2P(x)
-(4x²-3x+2)+2*(2x³-7x+3)= -4x²+3x-2+4x³-14x+6= 4x³-4x²-11x+4
h)-2W(x)-3Q(x)
-2(3x³-4x²+5x-6)-3(4x²-3x+2)= -3x³+8x²-10x+16-12x²+9x-6=-3x³-4x²-x+10
