Question

3x(1+12x)-(6x-1)(6x+1)=2,5x​

Answer 1

Ответ:

x=2

Объяснение:

3x(1+12x)-(6x-1)(6x+1)=2,5x

Раскроем скобки

3x+36x^2-36x^2-1=2,5x

Уберём противоположные выражения +36x^2 и -36x^2

3x-1=2,5x

Перенесём неизвестное налево, известное направо.

3x-2,5x=1

Вычислим ответ

0,5x=1

x=2

Answer 2

To solve the equation 3x(1+12x) - (6x-1)(6x+1) = 2.5x, you can follow these steps:

1. Distribute the terms inside the parentheses:

   3x(1) + 3x(12x) - (6x)(6x) - (6x)(1) + 2.5x = 0

2. Simplify each term:

   3x + 36x^2 - 36x^2 - 6x + 2.5x = 0

3. Combine like terms:

   (3x - 6x + 2.5x) + (36x^2 - 36x^2) = 0

4. Combine like terms in the parentheses:

   -0.5x + 0 = 0

5. Simplify further:

   -0.5x = 0

6. Divide both sides by -0.5 to isolate x:

   x = 0

So, the solution to the equation is x = 0.
