Question

Find the product.
(u + v)^2
help please!

zehanz · Answer

(u+v)²=(u+v)(u+v)

Now FOIL and add like terms.

Better: These kind of things always give the same answer. If you learn them by heart, you can do it much quicker (mostly it is given as (a+b)²= ....)

anonymous · Answer

u2+ 2uv+v
u2+ 2uv+v2
u2+ 2uv+ 2v2
these are my options

anonymous · Answer

i dont know which one though

anonymous · Answer

do you know how to FOIL?

zehanz · Answer

You don't need options.
You have to do this yourself.
FOIL means: 
First: multiply first terms: u*u=u²
Outer: multiply outer terms: u*v=uv
Inner: multiply inner terms: v*u=uv
Last: multiply last terms: v*v=v²

Now add up: u²+uv+uv+v²=u²+2uv+v²
