Which shows 602  402 being evaluated using the difference of squares method? (4 points)
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

Best ResponseYou've already chosen the best response.0the general identity for the difference of 2 squares is a^2  b^2 = ( a + b)( a  b) where a and b are 2 numbers if you replace a by 60 and b by 40 you'll be able to work out the answer
