Question

IF THE GIVEN POLYNOMIAL p[x]=x^2-x+k HAS A ZERO WHICH IS 2.
THEN FIND THE VALUE OF k

Answer 1

Answer:

- 2

Step-by-step explanation:

p( x ) = x² - x + k

We know that

Zero of a polynomial is the value of x for which the polynomial becomes 0.

Given :

2 is a zero of p( x )

=> p( 2 ) = 0

=> 2² - 2 + k = 0

=> 4 - 2 + k = 0

=> 2 + k = 0

=> k = - 2

Therefore the value of k is - 2.
