The proof of the identity $4xy = (x + y)^2 - (x - y)^2$ is shown. Drag each explanation to the step of the proof that it justifies. Step 1 $4xy = (x + y)^2 - (x - y)^2$ Step 2 $4xy = x^2 + 2xy + y^2 - (x - y)^2$ Step 3 $4xy = x^2 + 2xy + y^2 - x^2 + 2xy - y^2$ Step 4 $4xy = x^2 - x^2 + 2xy + 2xy + y^2 - y^2$ Step 5 $4xy = 4xy$
