Даю 15 баллов! Решите уравнение: 4х(3х-1)-2х(6х+8)=5 Срочно! Помогите пожалуйста!

Answer 1

12х^2-4х-12х^2-16х-5=0
12х^2 сокращаешься.
-20х=5
Х=-5/20
Х=-0.25

Answer 2

$4x*(3x-1)-2x*(6x+8)=5$
$12x^{2}-4x-12x^{2}-16x=5$
$-20x=5$
$x=5:(-20)$
$x=-0,25$

Answer 3

Solving the Equation

To solve the equation 4x(3x-1)-2x(6x+8)=5, we can follow these steps:

1. Expand and simplify the equation. 2. Set the equation equal to zero. 3. Factorize the quadratic equation. 4. Solve for x.

Step 1: Expand and Simplify the Equation

Expanding the equation gives us: 12x^2 - 4x - 12x^2 - 16x = 5

Simplifying further, we get: -20x = 5

Step 2: Set the Equation Equal to Zero

By rearranging the equation, we get: -20x - 5 = 0

Step 3: Factorize the Quadratic Equation

The equation is already in linear form, so there's no need to factorize it.

Step 4: Solve for x

Solving for x, we get: x = -5/20

Simplifying, we find: x = -1/4

Therefore, the solution to the equation 4x(3x-1)-2x(6x+8)=5 is x = -1/4.

This solution is obtained by following the standard steps for solving a quadratic equation.
