Question

(9-x^ 2)/ 5 =1срочно пж​

Answer 1

Ответ:

x1=-2, x2=2

Объяснение:

(9-x^ 2)/ 5 =1 домножаем обе части на пять

9-x^ 2=5 переносим девятку направо

-x^ 2=-4 домножаем на минус один, чтобы убрать знаки

x^2=4

х1=-2

х2=2

Answer 2

To solve the equation (9 - x^2)/5 = 1, we can follow these steps:

1. Multiply both sides of the equation by 5 to eliminate the denominator: 5 * (9 - x^2)/5 = 1 * 5 9 - x^2 = 5

2. Move the constant term to the right side of the equation: -x^2 = 5 - 9 -x^2 = -4

3. Multiply both sides of the equation by -1 to make the coefficient of x^2 positive: -1 * (-x^2) = -1 * (-4) x^2 = 4

4. Take the square root of both sides of the equation: sqrt(x^2) = sqrt(4) x = ±2

Therefore, the solutions to the equation (9 - x^2)/5 = 1 are x = 2 and x = -2.
