Mathematicians often seek patterns to simplify their tasks. A great example is when they square binomials. Instead of writing the binomial twice and applying the usual methods, you can save time and effort by recognizing and using a specific pattern.

You're absolutely right! When squaring a binomial, mathematicians often use the **square of a binomial** formula to simplify the process. This pattern can save a lot of time and effort compared to multiplying the binomial by itself.

The formula for squaring a binomial \((a + b)^2\) is:

\[
(a + b)^2 = a^2 + 2ab + b^2
\]

Similarly, for \((a - b)^2\), the formula is:

\[
(a - b)^2 = a^2 - 2ab + b^2
\]

These patterns emerge from the distributive property but are used to quickly expand and simplify expressions.

### Example:
Let's square the binomial \((3x + 4)\):

Using the formula \((a + b)^2 = a^2 + 2ab + b^2\):

\[
(3x + 4)^2 = (3x)^2 + 2(3x)(4) + 4^2
\]
\[
= 9x^2 + 24x + 16
\]

This method is much faster and efficient compared to writing the binomial twice and applying the distributive property manually.
