Answer 1

200.
1) f(x)=(2x³-1)(x²+1)=(2*1³-1)(1²+1)=(2*1-1)(1+1)=(2-1)*2=1*2=2
2) f(x)=(3-x²)(4+x²)=(3-4)(4+4)=-1*8=-8
3) f(x)=(x³+x²)(x²-1)=((-1)³+(-1)²)((-1)²-1)=(-1+1)(1+1)=0
201.
1) f(x)=x²+1/x²-1 = (-2)²+1/(-2)²-1=4+1/4-1=5/3=1 2/3
2) f(x)=x²+1/x³+1=1²+1/1³+1=1+1/1+1=2/2=1
3) f(x)=3x-1/2x+1=3*2-1/2*2+1=5/5=1
