Which shows 602 - 402 being evaluated using the difference of squares method?

602 - 402 = (3600 + 1600) (3600 - 1600) = 10,400,000

602 - 402 = 3600 - 1600 = 2,000

602 - 402 = (60 - 40) 2 = 202 = 400

602 - 402 = (60 + 40) (60 - 40) = (100) (20) = 2,000

The right answer for the question that is being asked and shown above is that: "602 - 402 = (3600 + 1600) (3600 - 1600) = 10,400,000" The equation that shows 602 - 402 being evaluated using the difference of squares method is that 602 - 402 = (3600 + 1600) (3600 - 1600) = 10,400,000
