Question

Find the value of K if x-2 is a factor of x^2 -kx+10​

Answer 1

Step-by-step explanation:

f(x)=x-2

x=2

x^2-kx+10=0

(2)^2-2k+10=0

4+10-2k=0

-2k= -14

k=7

Answer 2

Answer:

7

Step-by-step explanation:

x-2 is a factor means

x-2=0 implies x=2 is zero of given polynomial by factor theorem

put x=2 in x^2 -kx+10

2^2 -2k + 10 = 0​

4-2k+10=0

14-2k=0

k=7
