Question

If the zero of the polynomial x² - 12x + k = 0 is the HCF (9, 18), then find the value of k *

1 point

-12

9

27

-18​

Answer 1

Answer:

First

the HCF of (9 , 18) is 9

that is zero of the polynomial given is 9

now putting the value in given Polynomial equation

I. e

9^2 -12*9+k =0

81-108+k=0

-27+K=0

I. e.

k=27

Hence the Value of K is 27

Answer 2

Answer:

27

Step-by-step explanation:

HCF of 9,18 is 9 highest common factor

then 9 factor is 1,3,9

18 factors is 1,2,3,6,9,18

in both 9 is highest common factor

substitute 9 in the x then

81-12×9+k=0

k=27
