Answer 2

Hey friend!

Actual Question : If one of the zeroes of  the polynomial p(x)= x² - x + k is 2 then the value of k is​?

Here is your answer:

Given,

→ p(x) = x² - x + k

→ 2 is a zero of p(x)

We know that

If a is a zero of p(x)

→ then, p(a) = 0

$According\ to\ the\ Question:\\\\p(2) = 0\\\\\implies 2^2 - 2 + k = 0\\\\\implies 4 - 2 + k = 0\\\\\implies 2 + k = 0\\\\\implies k = -2$

∴ Answer:  k = - 2

I hope it helps you
