Answer 2

To make the equation valid, you need to replace "*" with "2ab". The correct equation is:

a^2 + 2ab + b^2 = (a + b)^2

This equation is a representation of the algebraic identity known as the square of a binomial. It states that the square of the sum of two terms (a and b) is equal to the sum of the squares of the individual terms (a^2 and b^2) plus twice the product of the two terms (2ab).
