1. Let's clarify the problem: you want to know what to put in the squares, which usually means filling in missing values or expressions in a math problem involving squares or square terms. 2. If this is about algebraic expressions with squares, such as $x^2$, the value inside the square is the base or the number being squared. 3. For example, in $\square^2 = 16$, the square root of 16 is 4, so the value to put in the square is 4 or -4 because $4^2 = 16$ and $(-4)^2 = 16$. 4. If you have an equation like $(\square + 3)^2 = 25$, you first take the square root of both sides: $\square + 3 = \pm 5$. 5. Then solve for the square: $\square = 5 - 3 = 2$ or $\square = -5 - 3 = -8$. 6. In general, to find what goes in the square, identify the expression inside the square, use inverse operations like square roots, and solve for the unknown. If you provide the exact problem or equation, I can give a more precise answer.
