Question

X^2-6x=4x-25 пж дискременант и x1,2

Answer 1

Ответ: 5

Пошаговое объяснение:

x²- 6x - 4x + 25 = 0

x² - 10x + 25 = 0

D = 100 - 100 = 0

x = 10 ÷ 2 = 5

Answer 2

X^2-10x+25=0
D=0 1 корень
x=5

Answer 3

To find the discriminant and the solutions for the equation x^2 - 6x = 4x - 25, we need to rewrite it in standard quadratic form, which is ax^2 + bx + c = 0.

First, move all the terms to the left side of the equation:

x^2 - 6x - (4x - 25) = 0

Next, simplify the equation:

x^2 - 6x - 4x + 25 = 0

Combine like terms:

x^2 - 10x + 25 = 0

Now, we can identify the values of a, b, and c for the standard quadratic equation:

a = 1 (coefficient of x^2) b = -10 (coefficient of x) c = 25

Now, we can calculate the discriminant (D):

D = b^2 - 4ac

Substitute the values:

D = (-10)^2 - 4 * 1 * 25 D = 100 - 100 D = 0

The discriminant (D) is equal to 0.

Now, let's find the solutions for x using the quadratic formula:

The quadratic formula is given by:

x = (-b ± √D) / 2a

Since the discriminant (D) is 0, we get only one real root:

x = (-(-10) ± √0) / 2 * 1 x = (10 ± 0) / 2 x = 10 / 2 x = 5

So, the only solution for the equation x^2 - 6x = 4x - 25 is x = 5.
