Question

25x^2=1 как это решить

Answer 1

смотри

извлекаешь корень из первой и второй части уравнения

получаешь 5x=1, откуда

x=1/5

вот и все

Answer 2

x²=1/25

x=$\sqrt{1/25}$

X=1/5

Answer 3

To solve the equation 25x^2 = 1, you need to isolate the variable x. Here's a step-by-step solution:

Step 1: Get rid of the constant term on the right side by subtracting 1 from both sides of the equation: 25x^2 - 1 = 0

Step 2: Now, you have a quadratic equation in the form of ax^2 + bx + c = 0, where a = 25, b = 0, and c = -1.

Step 3: To solve the quadratic equation, you can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / 2a

Plugging in the values, we get: x = (0 ± √(0^2 - 4 * 25 * -1)) / 2 * 25 x = (0 ± √(0 + 100)) / 50 x = (0 ± √100) / 50 x = (0 ± 10) / 50

Now, we have two possible solutions for x:

1. x = (0 + 10) / 50 x = 10 / 50 x = 1/5

2. x = (0 - 10) / 50 x = -10 / 50 x = -1/5

So, the solutions to the equation 25x^2 = 1 are x = 1/5 and x = -1/5.
