1652-1232=420. There are a lot of way to find the two products that equal to each other. For example, 2×210=420 84×5=420 840×1/2=420 ETC. Hope it help!
The question is actually 165^2 − 123^2, which wasnt shown in the original question so the brainliest answer is WRONG because they didnt know the 2s werent actually part of the equation!
