Answer 1

Answer:

b. -11

Step-by-step explanation:

replace all x with -1

Answer 2

Answer:

Step-by-step explanation:

4.p(x)=x³-x²+x+1

p(1)=1-1+1+1=2

p(-1)= -1-1-1+1= -2

So p(1)+p(-1) /2=2-2/2=0

ans c

2x³-3x²+4x-2

P(-1)=2(-1)³-3(-1)²+4(-1)-2

=-2-3-4-2

=-11 (b)

******************

let x^1/3=a ,y^1/3=b and z^1/3=c

so a+b+c=0

Thus we know that

a³+b³+c³=3abc

putting value

x+y + z =3{ x^1/3 y^1/3z^1/3] option(b)
