Question

6.15 2) (3х-1)* (х-2) =х-2х(х-4)​

Answer 1

Ответ:

Ну вот

Пошаговое объяснение:

(3x-1)*(x-1)=x-2x(x-4)

3$x^{2}$-6x-x+2=x-2$x^{2}$+8x

5$x^{2}$-16x+2=0

x=$\frac{-(-16)±\sqrt{(-16)^{2}-4*5*2 } }{2*5}$

x1≈0.130306

x2=3.06969

Answer 2

Let's simplify the given equation step by step:

(3x - 1) * (x - 2) = x - 2x(x - 4)

First, let's apply the distributive property on the left side of the equation:

3x * (x - 2) - 1 * (x - 2) = x - 2x(x - 4)

Now, we can simplify each term:

3x^2 - 6x - x + 2 = x - 2x^2 + 8x

Combining like terms:

3x^2 - 7x + 2 = x + 6x^2

Rearranging the terms to have zero on one side:

3x^2 - 7x + 2 - x - 6x^2 = 0

Combining like terms again:

-3x^2 - 8x + 2 = 0

This is a quadratic equation in standard form. We can solve it using factoring, completing the square, or the quadratic formula. However, it seems there might be an error in the initial equation. Please double-check your original equation to ensure its accuracy.
