2x -6x-24=0

Answer 2

Let's solve the equation step by step:

Given equation: 3x(x - 2) - x(3 + x) = -2(x - 4) - 4

Step 1: Distribute the terms on both sides of the equation.

3x^2 - 6x - 3x^2 - x^2 = -2x + 8 - 4

Step 2: Combine like terms on each side of the equation.

-4x^2 - 2x = -2x + 4

Step 3: Subtract -2x from both sides of the equation to eliminate the -2x term on the right side.

-4x^2 - 2x + 2x = 4

Simplify:

-4x^2 = 4

Step 4: Divide both sides of the equation by -4.

x^2 = -1

Step 5: Take the square root of both sides of the equation.

x = ±√(-1)

Since the square root of -1 is imaginary, there are no real solutions to this equation.

Therefore, the given equation does not have any real solutions.
