Answer 2

It looks like you have an equation with some missing values. Let's solve it step by step.

The equation you provided is: (5 + ...)² = ... + ... + a²

To solve for the missing values, we'll break it down:

1. Start with the left side of the equation: (5 + ...)²

To expand this expression, you can use the formula for squaring a binomial: (a + b)² = a² + 2ab + b²

In your case, a = 5, and b is the missing value, so let's call it x: (5 + x)² = 5² + 2 * 5 * x + x²

Now, we have a quadratic equation: 25 + 10x + x²

2. Now, let's move to the right side of the equation: ... + ... + a²

Since you want to express this as a sum of squares, let's say there are n terms (you can replace n with the appropriate number): a² + a² + a² + ... + a² (n times)

So, the right side becomes: n * a²

3. Equate the two sides of the equation: We can now set the left side equal to the right side and solve for x: 25 + 10x + x² = n * a²

Please provide values for a, n, or additional information to continue solving this equation or find specific values for x.
