Объяснение:

9-x=(3-√x)(3+√x)     ;    якщо х > 0

Answer 2

Factoring the Expression 9 - x (if x > 0)

To factor the expression 9 - x, where x > 0, we can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). In this case, we can rewrite 9 - x as 3^2 - x^2, where a = 3 and b = x. Applying the difference of squares formula, we get:

9 - x = (3 + x)(3 - x)

This is the factored form of the expression 9 - x when x is greater than 0.
