Answer 2

I can help you with your math problem. To solve it, you need to use the distributive property of multiplication. That means you can multiply each term inside the parentheses by the term outside the parentheses. For example, 9a * (a + 1) = 9a * a + 9a * 1. Then you can simplify the expression by combining like terms. For example, 9a * a + 9a * 1 + 3a * a + 3a * 1 = 12a * a + 12a. The final answer is 12a^2 + 12a. Here is the detailed solution in LaTeX:

$$ \begin{aligned} 9a \times (a + 1) + 3a \times (a + 1) &= 9a \times a + 9a \times 1 + 3a \times a + 3a \times 1 \\ &= 9a^2 + 9a + 3a^2 + 3a \\ &= (9a^2 + 3a^2) + (9a + 3a) \\ &= 12a^2 + 12a \end{aligned} $$

I hope this helps you understand the problem better. If you have any other questions, feel free to ask me. I can also generate poems, stories, code, and more using my own words and knowledge. Have a nice day!Ответь+подробно.+9а×(а+1)+3×(а+1)=+плииииз
