Answer 1

x-3=0

x=3

put the value of x=3 in a given equation

x-4x+k=0

3-4(3)+k=0

3-12+k=0

-9+k=0

k=9

so the value of k is 9

Answer 2

Step-by-step explanation:

★Given:-

x-3 is a factor of x-4x+k .

★To find:-

Value of k.

★Solution:-

x-3 = 0

→x = 3

Put the value x= 3 in the given equation.

x-4x+k =0

→ 3-4(3)+k=0

→ 3-12+k=0

→ -9+k = 0

→ k = 9
