Step-by-step explanation:
sol= x+1 =0
= x= –1
(I) Now,
x³+x²+x+1
p(x) =(-1)³+(-1)²+(-1)+1
p(x) = -1+1+(-1)+1
p(x) =0+0
p(x) =0
(ii) x⁴+x³+x²+x+1
Now,
p(x) = (-1)⁴+(-1)³+(-1)²+(-1)+1
p(x) = 1+(-1)+1+(-1)+1
p(x) = 1+1+1
p(x) = 3
(iii) x⁴+3x³+3x²+x+1
Now,
p(x) = (-1)⁴+3(-1)³+3(-1)²+(-1)+1
p(x) = 1+3+3-1+1
p(x) = 1+3+3
p(x) = 7
(iv) x³-x²-(2+√2)x+√2
Now,
p(x) = (-1)³-(-1)²-(2+√2)(-1)+√2
p(x) = -1-1+2+√2+√2
p(x) = -2+2+2√2
p(x) = 2√2
p(x) ≠ 0
