Question

Здравствуйте, перехожу в 7 класс. Сам придумал задачу и получил квадратное уравнение (предполагал, что так и получится). Сколько не разбирался в них, никогда не получалось. Решите мне такое уравнение: 20+x=/ Просьба подробно с объяснением, чтобы я опять мог попытаться разобраться в уравнение ещё раз.

Answer 1

$20+x= \sqrt{ x^{2}+ 25^{2} }$
$(20+x)^{2} = x^{2} + 25^{2}$
$400+40x+ x^{2} = x^{2} +625$
400+40x=625
40x=225
x=5,625

Answer 2

Answer 3

Solving the Quadratic Equation:

To solve the quadratic equation 20x = 0, we can use the standard form of a quadratic equation, which is ax^2 + bx + c = 0. In this case, the equation is already in a form that can be easily solved.

Solution Steps:

1. Isolating x: To solve for x, we need to isolate it on one side of the equation. In this case, we can simply divide both sides by 20 to isolate x.

2. Applying the Operation: Dividing both sides of the equation by 20 will give us the value of x.

Solution:

The solution to the equation 20x = 0 is: x = 0

This means that the value of x that satisfies the equation is 0.

I hope this explanation helps you understand how to solve this type of equation! If you have any more questions or need further clarification, feel free to ask.
