Question

HELP PLEASE? I'm very confused.

prove that (x+y)^2+(x^2+2xy+y^2) = x^4+2xy^3+y^4

How do I do this?

Answer 1

Answer 2

you sure that's right ?!

you posted \((x+y)^2+(x^2+2xy+y^2)\) which is \((x+y)^2 + (x+y)^2 \)

no \(x^{4}\) there

Answer 3

It was a question on my homework assignment, which is exactly why I posted it, because I wasn't sure it made sense.

Answer 4

As written these are not the same expression:

(x+y)^2+(x^2+2xy+y^2) = x^4+2xy^3+y^4

Consider posting a screenshot of the problem.

Something was lost between copy and paste. @MckennaRian
