Bei noticed that ( x 2)(y 2) = 4 is an equivalent algebraic representation of the four problems. Verify this equivalence with at least one other variation of the equations used for the collection of problems. Then, use this algebraic representation to justify why it makes sense that x= 3, x= 4, and x= 6 are the only integer values for which this equation is true. Hint: What does this equation say about the numbers represented by x 2 and y 2 in relationship to 4
