Question

verify whether the values of X given in each cases are the zeros of the polynomial or not?

Answer 1

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

= 1 - 1

f(1/2) = 0

Hence 1/2 is the zero of polynomial.

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

= -1 -1

f(-1/2) = -2

Hence it is not the zero of polynomial.



Thanks

Answer 2

yes for x=1/2

function value is 0
