Answer 1

Ответ:

-10

Объяснение:

8х^3-27-8х^3=2.7х

-2.7х=27

х=-10

Answer 2

To solve the equation (2x-3)(4x²+6x+9)-8x²=2.7x, let's simplify the left side of the equation first:

(2x - 3)(4x² + 6x + 9) - 8x² = 2.7x

Expanding the parentheses:

8x³ + 12x² + 18x - 12x² - 18x - 27 - 8x² = 2.7x

Combining like terms:

8x³ + (12x² - 12x² - 8x²) + (18x - 18x) - 27 = 2.7x

Simplifying further:

8x³ - 8x² - 27 = 2.7x

To solve for x, we'll bring all the terms to one side of the equation:

8x³ - 8x² - 2.7x - 27 = 0

Unfortunately, this equation cannot be solved directly using simple algebraic methods. We can use numerical methods such as graphing or numerical approximation techniques to find the approximate solutions.
