I believe it is wx^2 - 2ywx + y^2 ;
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
The expansion of ( w x − y ) 2 is done using the square of a binomial formula, resulting in w 2 x 2 − 2 w x y + y 2 . This involves squaring each term and accounting for their product. The expanded form provides a clearer view of the expression's components.
