Respuesta :
(r + s)^2
= r(r + s) + s(r + s)
= r^2 + rs + rs + s^2
= r^2 + 2rs + s^2 Answer
Is choice 2.
= r(r + s) + s(r + s)
= r^2 + rs + rs + s^2
= r^2 + 2rs + s^2 Answer
Is choice 2.
Answer:
[tex]r^2+2rs+s^2[/tex]
Step-by-step explanation:
we can see this [tex](r + s)^2[/tex] as (r+s)(r+s)
And simplify it using the concept of FOIL
so
[tex](r+s)(r+s)=r^2+rs+rs+s^2[/tex]
which further simplifies to
[tex]r^2+2rs+s^2[/tex]
