są wielomiany W(x)=2x²-3
P(x)=4x⁴-3x³ +2x-5
Z(x)= -3x³ +2x²-5 .
Wykonaj działania:
a) [(W(x)]² + 2P(x)=(2x²-3 )² + 2*(4x⁴-3x³ +2x-5 ) =
= 4x⁴- 12x² +9 +2x⁴-6x³ + 4x -10 =
= 6x⁴-6x³ -12x² + 4x -1
b) Z(x)-3P(x)= -3x³ +2x²-5 - 3*( 4x⁴-3x³ +2x-5 ) =
= -3x³ +2x²-5 -12x⁴+9x³-6x +15=
= -12x⁴+ 6x³ +2x² -6x +10
