Answer 2

It seems like you've provided an equation, but the notation is a bit unclear. Let's try to clarify it and solve for x:

The equation you've given appears to be:

(2 * 4x - 1) - (0.2x - 5.76x^2) = 3

Let's simplify and solve it step by step:

1. Distribute the 2 on the left side:

   8x - 2 - (0.2x - 5.76x^2) = 3

2. Remove the parentheses on the left side:

   8x - 2 - 0.2x + 5.76x^2 = 3

3. Combine like terms on the left side:

   (8x - 0.2x) + (5.76x^2 - 2) = 3

   7.8x + 5.76x^2 - 2 = 3

4. Move all terms to the right side:

   7.8x + 5.76x^2 - 2 - 3 = 0

   7.8x + 5.76x^2 - 5 = 0

5. Now, we have a quadratic equation in the form of ax^2 + bx + c = 0, where a = 5.76, b = 7.8, and c = -5.

To solve this quadratic equation, you can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

Plugging in the values:

x = (-7.8 ± √(7.8² - 4 * 5.76 * (-5))) / (2 * 5.76)

Now, calculate the discriminant (the value inside the square root):

Discriminant = b² - 4ac Discriminant = (7.8)² - 4 * 5.76 * (-5)

Calculate the discriminant, and then use the quadratic formula to find the values of x. Keep in mind that there may be two solutions for x (one for each ± in the formula) unless the discriminant is negative, in which case there would be no real solutions.
