## help_people one year ago 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

do you mean: evaluate $$60^2-40^2$$ using the difference of squares method?

3. anonymous

if so, you can factor...$60^2-40^2=\left( 60-40 \right)\left( 60+40 \right)$
