Question

Can someone solve this for me? Common factor first! Thank you.

Answer 1

`\boxed{\sf \ \ \ 5(x-4)^2 \ \ \ }`

Explanation:

hello

step 1 - divide by 5

`5x^2-40x+80=5(x^2-8x+16)`

step 2 - solving the square

`(x-4)^2=x^2-8x+16`

Finally, to answer the question

`5x^2-40x+80=5(x-4)^2`

hope this helps

Answer 2

`5 {(x - 4)}^(2)`

Explanation:

`5 {x}^(2) - 40x + 80 \\ =5( {x}^(2) - 8x + 16) \\ = 5 ( {x}^(2) - 8x + {4}^(2) ) \\ = 5 {(x - 4)}^(2)`
