1. dane są wielomiany W(x) =x(@3) + 3x(@2) + 4x-2 G (x)= 2x (@3)-5x (@2) + 3x+7 2. wyznacz wielomian 2 W(x) +3G(x) a) oblicz W(2) Objasnienie [email protected] to x do drugiej a [email protected] do trzeciej :)

do 1-go. 2(x3 +3x2+4x-2) +3(2x3-5x2+3x+7)=2x3+6x2+8x-4+6x3-15x2+9x+21=8x3-9x2+17x+17
do 2-go. W(2)=8+12+8-2=26.:)
