​

Answer 1

Answer:

k=(4,4)

Step-by-step explanation:

(k-4)^2=k^2-2(k)(4)+(4)^2

=k^2-8k+16

=(k-4)(k-4)

so ,k=(4 ,4)

using (a-b)^2 formula

Answer 2

Answer:

hey here is your answer..

Step-by-step explanation:

• (k - 4)²
• (k - 4)(k -4)
• k² - 4k - 4k + 16
• k² + 8k + 16

______________∆______________

• k² + 8k + 16
• k² + 4k + 4k + 16
• k ( k + 4) + 4 ( k + 4)
• ( k + 4)( k + 4)
• k = -4 , -4
