a) w(x)+q(x)=2x³-14x²+14x+30+x²-2x-3= 2x³-13x²+12x+27
b) w(x)-q(x)= 2x³-14x²+14x+30-x²+2x+3=2x³-16x²+16x+33
c) w(x)×q(x)=(2x³-14x²+14x+30)(x²-2x-3)=
2x⁵-4x⁴-6x³-14x⁴+28x³+42x²14x³-28x²-42x+30x²-60x-90
=2x⁵-18x⁴+22x³+30x²-102x-90
d)w(x)÷q(x)=( 2x³-14x²+14x+30)÷(x²-2x-3)=2x-10
2x-10
-----------------------
(2x³-14x²+14+30) ÷ (x²-2x-3)
-2x³+4x²+6x
