Explain the Error. Marco wrote the expression (2x - 7y) 2 = 4x² - 49y² . Explain and correct his error.

Marco may have confused a difference of squares and the square of a binomial difference. He wrote the difference of the squares of the terms instead of square of a binomial difference. The correct product is 4x² - 28xy + 49y².
