$$ \text{Find } 2011^2 - 2010^2 \text{?} $$

Question

UpStudy AI · Accepted Answer

To find $$ 2011^2 - 2010^2 $$, we can use the **difference of squares** formula:

$$
a^2 - b^2 = (a + b)(a - b)
$$

Let $$ a = 2011 $$ and $$ b = 2010 $$. Applying the formula:

$$
2011^2 - 2010^2 = (2011 + 2010)(2011 - 2010)
$$

Calculate the sums and differences:

$$
2011 + 2010 = 4021
$$
$$
2011 - 2010 = 1
$$

Now, multiply them together:

$$
4021 \times 1 = 4021
$$

**Answer:** $$ 4021 $$
$$ 2011^2 - 2010^2 = 4021 $$
