Question

Выполните умножения многочленов(х-2)•(х+2) ​

Answer 1

Ответ:

(x-2)(x+2)=x²-2²=x²-4

Объяснение:

(a-b)(a+b)=a²-b²

Answer 2

Объяснение:

$x {}^{2} + 2x - 2x - 4 = x {}^{2} - 4$

Answer 3

Multiplying Polynomials

To multiply the polynomials (x-2) and (x+2), we can use the distributive property to expand the expression. The result will be a new polynomial.

The process of multiplying the polynomials (x-2) and (x+2) can be represented as follows: ``` (x-2) * (x+2) = x*(x+2) - 2*(x+2) ``` Expanding this further: ``` = x*x + x*2 - 2*x - 2*2 = x^2 + 2x - 2x - 4 = x^2 - 4 ``` Therefore, the product of (x-2) and (x+2) is x^2 - 4.
