Question

3x²=18x дискриминант пж помогите ​

Answer 1

Ответ:

здесь не нужен дискриминант.

Answer 2

Ответ:

0; 6

Объяснение:

$3x {}^{2} = 18x.$

• Разделим обе части уравнения на 3.

$x {}^{2} = 6x.$

• Переносим одночлен 6х влево, знак меняем.
• ${x}^{2} - 6x = 0.$
• Выносим общий множитель "х" за скобки.

$x(x - 6) = 0.$

• Произведение равно 0, когда хотя бы 1 из множителей равен 0.

$x = 0. \\ x = 6.$

***Квадратное уравнение неполное, дискриминант не нужен***

Answer 3

Solving the Quadratic Equation 3x² = 18x

To solve the quadratic equation 3x² = 18x, we can start by rearranging the equation into the standard form of a quadratic equation, which is ax² + bx + c = 0. In this case, we have: 3x² - 18x = 0

Finding the Discriminant

The discriminant (denoted as Δ) of a quadratic equation in the form ax² + bx + c = 0 is given by the formula: Δ = b² - 4ac

In our case, the coefficients are: a = 3 b = -18 c = 0

Substitute these values into the discriminant formula: Δ = (-18)² - 4(3)(0)

Solving this, we get: Δ = 324

Conclusion

The discriminant of the quadratic equation 3x² = 18x is 324.
