Answer 3

A^2 + a^2 = A*A + a*a = (A + a)(A - a)

This is known as the difference of squares formula. It states that the square of a binomial (A + a)(A - a) is equal to the square of the first term (A) minus the square of the second term (a).

For example, if A = 5 and a = 3, then:

A^2 + a^2 = 5^2 + 3^2 = 25 + 9 = 34
