Question

5x -4x ·3x +2x +x =1 +2 +3 +4 -5

Answer 1

8x-12x=5
-4x=5
x= -1,25

Answer 2

Let's simplify the expression step by step:

5x - 4x · 3x + 2x + x = 1 + 2 + 3 + 4 - 5

First, let's solve the left side of the equation:

Combine like terms on the left side: (5x - 4x) · 3x + 2x + x = 6x · 3x + 2x + x x · 3x + 2x + x = 6x^2 + 2x + x

Now, the equation becomes: 6x^2 + 2x + x = 1 + 2 + 3 + 4 - 5

Combine like terms on the right side: 6x^2 + 2x + x = 5

Now, we have a quadratic equation. Let's solve for x:

Combine like terms on the left side: 6x^2 + 3x = 5

Move all terms to one side to set the equation to zero: 6x^2 + 3x - 5 = 0

Now, we need to solve this quadratic equation. We can do this using the quadratic formula:

The quadratic formula is given as: x = (-b ± √(b^2 - 4ac)) / 2a

In our case, a = 6, b = 3, and c = -5:

x = (-(3) ± √(3^2 - 4(6)(-5))) / 2(6) x = (-3 ± √(9 + 120)) / 12 x = (-3 ± √129) / 12

Therefore, the solutions for x are: x = (-3 + √129) / 12 x = (-3 - √129) / 12

These are the two possible values of x that satisfy the original equation.
