Question

Перетворіть у многочлен. (0,2а+0,3в)²

Answer 1

(0,2а+0,3в)²= 0,04а² + 0,12ав+0,09в²

Answer 2

I can help you with your math question. To convert the expression (0,2а+0,3в)² into a polynomial, you need to use the formula (a+b)²=a²+2ab+b². In this case, a=0,2а and b=0,3в. So, you get:

(0,2а+0,3в)²=(0,2а)²+2(0,2а)(0,3в)+(0,3в)²

Now, you need to simplify each term by multiplying the numbers and the variables. You get:

(0,2а+0,3в)²=0,04а²+0,12ав+0,09в²

This is the final answer. It is a polynomial of degree 2, because the highest power of the variables is 2. You can learn more about polynomials from [this website](https://www.evkova.org/mnogochlenyi). I hope this helps.
