The false position method, also known as the regula falsi method, is an iterative method for finding roots of a function. The method requires two initial guesses, $x_0$ and $x_1$, such that $f(x_0)$ and $f(x_1)$ have opposite signs. We use the formula for the next approximation $x_2$ given by:

$x_2 = x_1 - \frac{f(x_1)(x_1 - x_0)}{f(x_1) - f(x_0)}$

For the given equation $2x^2 - 3 = 0$, let $f(x) = 2x^2 - 3$. We need to find the roots of this function.

Let's follow the steps of the false position method:

1. Choose initial guesses: Let's select $x_0 = 1$ and $x_1 = 2$.

2. Evaluate the function at these points: $f(x_0) = 2(1)^2 - 3 = 2 - 3 = -1$ $f(x_1) = 2(2)^2 - 3 = 8 - 3 = 5$

3. Calculate $x_2$ using the false position formula: $x_2 = x_1 - \frac{f(x_1)(x_1 - x_0)}{f(x_1) - f(x_0)}$ $x_2 = 2 - \frac{5(2 - 1)}{5 - (-1)}$ $x_2 = 2 - \frac{5 \times 1}{6}$ $x_2 = 2 - \frac{5}{6}$ $x_2 = 2 - 0.8333 = 1.1667$

4. Evaluate the function at the new point $x_2$: $f(x_2) = 2(1.1667)^2 - 3$ $f(x_2) = 2(1.3611) - 3$ $f(x_2) = 2.7222 - 3 = -0.2778$

Since $f(x_2)$ has opposite signs to $f(x_1)$, we update our guesses: now $x_0 = 1.1667$ and $x_1$ remains 2.

5. Repeat the process:

   Calculate the next approximation $x_3$: $x_3 = x_1 - \frac{f(x_1)(x_1 - x_0)}{f(x_1) - f(x_0)}$ $x_3 = 2 - \frac{5(2 - 1.1667)}{5 - (-0.2778)}$ $x_3 = 2 - \frac{5 \times 0.8333}{5.2778}$ $x_3 = 2 - \frac{4.1665}{5.2778}$ $x_3 = 2 - 0.7896 = 1.2104$

6. Evaluate the function at the new point $x_3$: $f(x_3) = 2(1.2104)^2 - 3$ $f(x_3) = 2(1.4651) - 3$ $f(x_3) = 2.9302 - 3 = -0.0698$

Continue this iterative process until $f(x_n)$ is sufficiently close to zero (within a desired tolerance).

Summary: Using the false position method iteratively refines the estimate of the root. After several iterations, the values will converge to the root of the equation $2x^2 - 3 = 0$. The exact root can be found by continuing this process or switching to another method for further refinement.

Tip: When using iterative methods like the false position method, it's important to establish a stopping criterion, such as a maximum number of iterations or a desired tolerance level for the function value. This helps ensure that the method terminates within a reasonable timeframe and provides an accurate approximation of the root.
