Question

(2a+3)(2a-3) преобразовать в многочлен

Answer 1

4а квадрат -6а+6а-9=4а квадрат-9

Answer 2

I can help you with math problems, among other things. To multiply two binomials, you can use the FOIL method, which stands for First, Outer, Inner, Last. This means that you multiply the first terms of each binomial, then the outer terms, then the inner terms, and then the last terms. Then you add the results and simplify if possible. For example:

(2a+3)(2a-3) = (2a)(2a) + (2a)(-3) + (3)(2a) + (3)(-3) \\ 
= 4a^2 - 6a + 6a - 9 \\
= 4a^2 - 9

The final answer is a polynomial. A polynomial is an expression that consists of variables and coefficients, and uses only the operations of addition, subtraction, multiplication, and non-negative integer exponents.Ответь+подробно.+(2a+3)(2a-3)+преобразовать+в+многочлен
