Question

Verify that -1, 1/2,1/3 are the zeroes of the polynomial 6x3 + x2 – 4x + 1 and verify the relationship between the zeroes and the coefficients.(A)

Answer 1

Answer:

1) if x= -1 then,

6(-1)^3+(-1)^2-4(-1)+1= -6+1+4+1=0

so it is zero of the polynomial

2) if x=1/2 then

6(1/2)^3+(1/2)^2-4(1/2)+1= 3/2+1/4-1/2+1 =9/4

so it is not

3) it is not factor of 1/3 if we substitute answer will not come
