Question

Which shows 51^2 - 49^2 being evaluated using the difference of squares method?

51^2 - 49^2 = 2601 - 2401 = 200

51^2 - 49^2 = (51 + 49)(51 - 49) = (100)(2) = 200

51^2 - 49^2 = (51 - 49)^2 = 2^2 = 4

51^2 - 49^2 = (2601 + 2401)(2601 - 2401) = 1,000,400

Answer 1

\(\large a^2 - b^2 = (a+b)(a-b)\)

a = 51, b = 49.

Answer 2

Okay?

Answer 3

A IS THE CORRECT ANSWER

Answer 4

Thanks

Answer 5

\(\large a^2 - b^2 = (a+b)(a-b)\)
Therefore, \(\large 51^2 - 49^2 = (51+49)(51-49) = 100*2 = 200\)

The correct answer is B.
