Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the provided equation and standardize it.
  • Step 2: Determine the coefficients aa, bb, and cc.
  • Step 3: Compute the discriminant b24acb^2 - 4ac.
  • Step 4: Analyze the discriminant to determine the nature of the solutions.

Let's work through each step:

Step 1: The given equation is x22x+23=0\frac{x^2}{2} - x + \frac{2}{3} = 0. For simplicity, we multiply through by 6 to clear fractions:
This becomes 3x26x+4=03x^2 - 6x + 4 = 0.

Step 2: Identify coefficients for the quadratic formula:
a=3a = 3, b=6b = -6, and c=4c = 4.

Step 3: Compute the discriminant b24acb^2 - 4ac:
Discriminant =(6)24×3×4=3648=12= (-6)^2 - 4 \times 3 \times 4 = 36 - 48 = -12.

Step 4: Analyze the discriminant:
The discriminant is negative (12-12), indicating no real solutions.

No solution exists for this equation in the real number set.

Therefore, the solution to the problem is: No solution.

Answer

No solution
