To expand , we can use the binomial theorem or simply apply the formula for squaring a binomial: . Here, and . So we have:

Calculating this gives:

Hence, the expanded form is .

Now let’s say you want to visualize this expression’s growth. By plugging in different values for , you can see how quickly it rises, especially for larger values of . For example, if , the result is significantly larger compared to smaller values.

It’s crucial to remember that squaring a binomial involves careful multiplication. A common mistake is to simply square the first and last term without including the middle term’s contribution (the part). Always double-check your work by redoing the multiplication step if you’re in doubt!
