Question

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

Answer 1

Answer:

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

Step-by-step explanation:

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

Answer 2

Answer:

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

Step-by-step 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
