## Simplifying (y - 7)^2

The expression (y - 7)^2 represents the square of the binomial (y - 7). To simplify it, we can use the following steps:

### Understanding the Concept

The expression (y - 7)^2 is equivalent to multiplying (y - 7) by itself:

**(y - 7)^2 = (y - 7) * (y - 7)**

### Expanding the Expression

We can use the distributive property (also known as FOIL) to expand the expression:

**F**irst: y * y = y^2**O**uter: y * -7 = -7y**I**nner: -7 * y = -7y**L**ast: -7 * -7 = 49

Combining the terms, we get:

**y^2 - 7y - 7y + 49**

### Simplifying the Result

Finally, we combine the like terms:

**y^2 - 14y + 49**

### Final Answer

Therefore, the simplified form of (y - 7)^2 is **y^2 - 14y + 49**.
