Question

Which shows 532 - 472 being evaluated using the difference of squares method?

532 - 472 = 2809 - 2209 = 600

532 - 472 = (53 + 47)(53 - 47) = (100)(6) = 600

532 - 472 = (53 - 47)2 = 62 = 36

532 - 472 = (2809 + 2209)(2809 - 2209) = 3,010,800

Answer 1

Which shows 53^2 - 47^2 being evaluated using the difference of squares method?

53^2 - 47^2 = 2809 - 2209 = 600

53^2 - 47^2 = (53 + 47)(53 - 47) = (100)(6) = 600

53^2 - 47^2 = (53 - 47)^2 = 6^2 = 36

53^2 - 47^2 = (2809 + 2209)(2809 - 2209) = 3,010,800
sorry posted and didnt relize it didnt put the powers in correctly

Answer 2

Difference of squares:
\[a^2-b^2 = (a+b)(a-b)\]
You have \(a = 53\) and \(b=47\)
