Question

245x°-120x – 125 = 0​

Answer 1

Ответ:

$x1 = 1 \\ x2 = - \frac{25}{49}$

Пошаговое объяснение:

$245 {x}^{2} - 120x - 125 = 0| \div 5 \\ 49 {x}^{2} - 24x - 25 = 0 \\ d = 576 + 4900 = 5476 \\ x1 = \frac{24 + 74}{98} = 1 \\ x2 = \frac{24 - 74}{98} = - \frac{25}{49}$

Answer 2

Ответ:

Пошаговое объяснение:

49x² - 24x - 25 = 0

D = 576 + 4900 = 5476 = 74²

x1 = (24 - 74)/98 = -50/98 = -25/49

x2 = (24 + 74)/98 = 1

Answer 3

To solve the equation 245x° - 120x - 125 = 0, we need to find the value(s) of x that satisfy the equation. Let's solve it step-by-step:

Step 1: Combine like terms on the left side of the equation: 245x - 120x - 125 = 0

Step 2: Simplify the equation: 125x - 125 = 0

Step 3: Add 125 to both sides of the equation to isolate the x term on one side: 125x = 125

Step 4: Now, to find the value of x, divide both sides of the equation by 125: x = 125 / 125

Step 5: Simplify: x = 1

The solution to the equation is x = 1.
