Question

9-x²=0 решите уравнения

Answer 1

$9 - {x}^{2} = 0 \\ (3 - x)(3 + x) = 0 \\ x = 3\\ x = -3$

Ответ: -3; 3.

Answer 2

Ответ:+-3

Объяснение:

9-х^2=0

(3+х)(3-х)=0

х=3

х=-3

Answer 3

To solve the equation 9 - x² = 0, we need to find the values of x that make the equation true.

Step 1: Move the constant term to the other side of the equation: x² = 9

Step 2: Take the square root of both sides of the equation: x = ±√9

Step 3: Simplify the square root: x = ±3

So, the solutions to the equation are x = 3 and x = -3.
