x^2-y^2+x+y
Transcript text: Factor by first grouping the appropriate terms.
\[
x^{2}-y^{2}+x+y
\]
Solution
Solution Steps
To factor the expression \(x^2 - y^2 + x + y\) by grouping, we can rearrange and group the terms in a way that allows us to factor them easily. We can group the terms as \((x^2 + x)\) and \((-y^2 + y)\), then factor each group separately. Finally, we combine the factored groups to find the overall factored form.
Step 1: Rearranging the Expression
We start with the expression:
\[
x^2 - y^2 + x + y
\]
We can rearrange it as:
\[
x^2 + x - y^2 + y
\]
Step 2: Grouping Terms
Next, we group the terms:
\[
(x^2 + x) + (-y^2 + y)
\]
Step 3: Factoring Each Group
Now, we factor each group:
\[
x(x + 1) - y(y - 1)
\]
This can be rewritten as:
\[
(x + y)(x - y + 1)
\]
Final Answer
The factored form of the expression is:
\[
\boxed{(x + y)(x - y + 1)}
\]
