Question
Verify whether the following zeroes of the polynomial, indicated against them.
p(x) = 2x + 1, `x = 1/2`
Advertisements
Solution
If `x = 1/2` is a zero of polynomial p(x) = 2x + 1, then `p(1/2)` should be 0.
Here, `p(1/2)=2(1/2)+1`
= 1 + 1
= 2
As `p(1/2)≠0`,
Therefore, `x = 1/2` is not a zero of the given polynomial.
