Answer 3

To solve the equation (2(4 - 5x))(4x - 1) + 2x(10x + 8,4) - 3,3 = 0, we need to simplify and solve for the value of x.

Let's break it down step by step:

1. Start by simplifying the expressions within the parentheses:

   2(4 - 5x) = 8 - 10x 2x(10x + 8,4) = 20x^2 + 16x

2. Rewrite the equation with the simplified expressions:

   (8 - 10x)(4x - 1) + (20x^2 + 16x) - 3.3 = 0

3. Now, we can expand and simplify the equation:

   (8 - 10x)(4x - 1) = 32x^2 - 8x - 40x + 10 = 32x^2 - 48x + 10

4. Rewrite the equation with the simplified expression:

   32x^2 - 48x + 10 + 20x^2 + 16x - 3.3 = 0

5. Combine like terms:

   52x^2 - 32.7 = 0

6. To solve for x, set the equation equal to zero:

   52x^2 - 32.7 = 0

7. Add 32.7 to both sides:

   52x^2 = 32.7

8. Divide both sides by 52:

   x^2 = 32.7 / 52

9. Take the square root of both sides:

   x = ±√(32.7 / 52)

10. Calculate the values of x:

x ≈ ±√(0.627)

So, the solutions for x are approximately:

x ≈ √0.627 and x ≈ -√0.627

These are the values of x that satisfy the given equation.
