Question

Simplify (x+y) 2 -(x-y) 2

Answer 1

This is in the form of a^2 - b^2 = (a + b) * (a - b)

Thus, (x + y)^2 - (x - y)^2 = (x + y + x - y) * (x + y - x + y)
                                                    = 2x * 2y
                                                    = 4xy

Thus, (x + y)^2 - (x - y)^2 = 4xy.

Answer 2

Answer:

(x-y)2=(x+y)2 answerd
