proszę o pomoc !! :)

1.Oblicz wartości podanych wielomianu w dla x = 0, x = 1, x = -2 i x = -3
w(x)=3x3-x2-2x-3
w(x)= -x4+5x3-4x2-6x+12
w(x)= 4x2-2x+7


2.Wyznacz wielomian v(x)= w(x) - 3g(x) gdy:
a) w(x)=x3-x+2x4-1 g(x)=4-x3+3x2+x4
b) w(x)= 3x6-2x4+5x2+4x3-x5-2x+5 g(x)= x5-6x2-1
5. Wyznacz sumę wielomianów u(x) + w(x) gdy:
a) u(x)= 17x4-14x2+7x-5-2x3 w(x)=6x3+11x2-5x+5-6x4
b) u(x)= 9x7-13x3+10x2-2 w(x)= -9x7+6x4-12x2+7
c) u(x) =4x2-5x+7 w(x)=5x3-3x2-3x+8
d) u(x)= x3-2x2+3x5-4-2x4-x w(x)= 3x2-2x4+4-x3-6x5+3x-1
e) u(x)= -2x6+4x3-8x+5 w(x)= x6-2x4+3x3-6x+2

3. Wykonaj iloczyn:
a) (x+2)(4x2-3x+4)=
b) (x2-5x+1)(x2+3x-4)=
c) (3x3-2x2+5x-1)(x2-6x-7)=
d) (6x-8)(3x+2) =
