$\left(x+y\right)^2+2x+2y+1$
Learn how to solve special products problems step by step online. Expand the expression (x+y)^2+2(x+y)+1. Multiply the single term 2 by each term of the polynomial \left(x+y\right). Expand the expression \left(x+y\right)^2 using the square of a binomial. Take the square of the first term: x. Twice (2) the product of the two terms: x and y.
