Dane są wielomiany:
W(x)=x^{4}-2x^{2}+1
Q(x)=-x^{4}+3x^{3}
P(x)=2x^{2}+3x-1
Wykonaj działania:
A) W(x)-Q(x)+P(x)=
B) 2*Q(x)+W(x)*P(x)=

A) W(x)-Q(x)+P(x)= x^{4}-2x^{2}+1 - (-x^{4}+3x^{3} ) + 2x^{2}+3x-1 =
x^4 + x^4 -3x^3 = 2x^4 -3x^3
B) 2*Q(x)+W(x)*P(x)=2*(-x^{4}+3x^{3} ) + (x^{4}-2x^{2}+1)(2x^{2}+3x-1) =
-2x^4+ 6x^3 + 2x^6 + 3x^5 - x^4 -4x^4 - 6x^3 + 2x^2 + 2x^2 + 3x - 1 = 2x^6 + 3x^5 - 7x^4 +4x^2 +3x -1
