Find the missing term
(x+y)squared = x squared + ____ + y squared
why don't you multiply
(x+Y)(x+y) to find that middle term?
To find the missing term in the expression (x+y)^2 = x^2 + ____ + y^2, you can expand the binomial (x+y)^2 using the formula for squaring a binomial:
(x+y)^2 = x^2 + 2xy + y^2
Therefore, the missing term in the expression is 2xy.
