Transcript text: Multiply using the rule for the product of the sum and difference of two terms.
\[
(6 x+7)(6 x-7)
\]
Solution
Solution Steps
The expression \((6x + 7)(6x - 7)\) can be simplified using the difference of squares formula, which states that \((a + b)(a - b) = a^2 - b^2\). Here, \(a = 6x\) and \(b = 7\).
Step 1: Identify the Expression
We start with the expression \((6x + 7)(6x - 7)\). This expression can be simplified using the difference of squares formula.
Step 2: Apply the Difference of Squares Formula
Using the formula \((a + b)(a - b) = a^2 - b^2\), we identify \(a = 6x\) and \(b = 7\). Thus, we can rewrite the expression as:
\[
(6x + 7)(6x - 7) = (6x)^2 - (7)^2
\]
Step 3: Calculate the Squares
Now, we calculate the squares:
\[
(6x)^2 = 36x^2 \quad \text{and} \quad (7)^2 = 49
\]
Substituting these values back into the expression gives us:
\[
36x^2 - 49
\]
Final Answer
The simplified expression is:
\[
\boxed{36x^2 - 49}
\]
