Question

verify whether the values of X given in each case are the zeros of the polynomial or not, f(x)=2x-1,x=1/2,-1/2
​

Answer 1

ANSWER:

f(X) = 2x - 1

By factor theorem,

f(1/2) = 2(1/2) - 1

= 1- 1

= 0

Therefore, f(1/2) is the factor of f(X).

f(-1/2) = 2(-1/2) - 1

= -1 - 1

= - 2 ≠ 0

Therefore, f(-1/2) is not the factor of f(X).

Hence, verified.
