Question

Factor the expression k^2+16k+64

Answer 1

`\red{(k + 8)(k + 8)}`

Answer 2

`\huge\boxed{\sf (k + 8)(k + 8)}`

Explanation:

Given expression:

`k^2+16k+64`

We can write it as:

`=(k)^2+2(k)(8)+(8)^2`

Using formula
`\bold{a^2+2ab+b^2=(a+b)^2}`

`=(k+8)^2`

= (k + 8)(k + 8)

`\rule[225]{225}{2}`
