Answer 1

Ответ:

Объяснение:

x² - 27 = 0

x² = 27

x = ±√27 = ±3√3

Answer 2

To solve the quadratic equation x² - 27 = 0, we can use the method of factoring:

Step 1: Move the constant term to the other side of the equation: x² = 27

Step 2: Take the square root of both sides to eliminate the square term: x = ±√27

Step 3: Simplify the square root of 27: x = ±√(9 * 3)

Step 4: Further simplify the square root: x = ±√9 * √3

Step 5: Calculate the square root of 9: x = ±3 * √3

Therefore, the solutions to the equation are: x = 3√3 (approximately 5.196) x = -3√3 (approximately -5.196)
