$x^2-4$

## Step-by-step Solution

Problem to solve:

$\left(x-2\right)\left(x+2\right)$
1

The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: $(a+b)(a-b)=a^2-b^2$, where:

• The first term ($a$) is $x$.
• The second term ($b$) is $2$.
Then:

$x^2-1\cdot 2^2$

$x^2-1\cdot 2^2$

Learn how to solve special products problems step by step online. Solve the product (x-2)(x+2). The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2, where:<ul><li>The first term (a) is x.</li><li>The second term (b) is 2.</li></ul>Then:. Calculate the power 2^2. Multiply -1 times 4.
