Kendall says the sum of (6x2 4xy 2y2) and (4x2 – 2xy – 3y2) is (10x2 2xy – 5y2). What error did Kendall make? He combined the like terms 6x2 and 4x2 incorrectly. He combined the like terms 4xy and –2xy incorrectly. He combined the like terms 2y2 and –3y2 incorrectly. He subtracted the polynomials instead of adding.
