Question

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

Answer 1

Объяснение:

(х + у)(х - у) + (х + у)² = (х + у) + (х - у + х + у) = 2х(х + у)

Если Вам нужно упростить,то :

(х + у)(х - у) + (х + у)² = х² - у² + х² + 2ху + у² = 2х² + 2ху

Answer 3

To simplify the expression (x+y)(x-y) + (x+y)^2, you can follow these steps:

1. Expand (x+y)(x-y): (x+y)(x-y) = x(x-y) + y(x-y)

2. Distribute x and y into (x-y): x(x-y) = x^2 - xy y(x-y) = yx - y^2

3. Add the results from step 2: (x+y)(x-y) = (x^2 - xy) + (yx - y^2)

4. Rearrange the terms: (x^2 - xy) + (yx - y^2) = x^2 + yx - xy - y^2

5. Expand (x+y)^2: (x+y)^2 = x^2 + 2xy + y^2

6. Add the result from step 5 to the result from step 4: (x^2 + yx - xy - y^2) + (x^2 + 2xy + y^2) = x^2 + yx - xy - y^2 + x^2 + 2xy + y^2

7. Combine like terms: x^2 + x^2 + 2xy - xy + yx + 2xy - y^2 + y^2 = 2x^2 + 3xy

So, the simplified expression is 2x^2 + 3xy.
