Answer 2

I can help you with your math problem.

The correct answer is D. Here is how you can solve it:

First, you need to factor out -5 from the expression:

$$ (a+b)^2 = -5a - 5b $$

$$ (a+b)^2 = -5(a + b) $$

Then, you can use the difference of squares formula to factor the left side:

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

$$ (a+b)(a+b) = -5(a + b) $$

Finally, you can divide both sides by (a + b) to get the final answer:

$$ \frac{(a+b)(a+b)}{(a + b)} = \frac{-5(a + b)}{(a + b)} $$

$$ (a+b) = -5 $$

Therefore, the original expression can be written as:

$$ (a+b)^2 = -5(a + b) $$

$$ (a+b)(a+b - 5) = 0 $$

I hope this helps. If you have any other questions, feel free to ask me.
