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

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

4x^ + 2xy + 2xy + y^ - x^ + 2xy + 2xy - 4y^

3x^ - 3y^ + 8xy , I believe ! I'm not 100% on this one though, sorry,!!

(^ is ^2 !!)

Answer:

(x+3, y+2)

Step-by-step explanation:

choose a letter: let's use points A and A'

A: (-3, 3)

A': (0, 5)

the rule would be (x+3, y+2) because (-3+3, 3+2) = (0,5)

Try it on another point:

B: (-4, 0)

B': (-4+3, 0+2) = (-1, 2) which checks out!
