Sagot :
i think that supposed to be (wx - y^2)^2?
If so, multiply using FOIL:
First: wx * wx = w^2x^2
Outside: wx * -y^2 = -wxy^2
Inside: -y * wx = -wxy^2
Last: -y^2 * -y^2 = y^4
Combine w^2x^2 - 2wxy^2 + y^4

Answer:
I believe it is wx^2 - 2ywx + y^2
Step-by-step explanation:
seperated into (wx-y)(wx-y) and used FOIL
