Let's solve the equation step by step:

Given equation:
\[
4x^2 - 9 + 3 = 0
\]

### Step 1: Simplify the equation
Combine like terms:
\[
4x^2 - 6 = 0
\]

### Step 2: Isolate \(x^2\)
Add 6 to both sides:
\[
4x^2 = 6
\]

### Step 3: Solve for \(x^2\)
Divide both sides by 4:
\[
x^2 = \frac{6}{4} = \frac{3}{2}
\]

### Step 4: Solve for \(x\)
Take the square root of both sides:
\[
x = \pm \sqrt{\frac{3}{2}} = \pm \frac{\sqrt{6}}{2}
\]

### Final Answer:
\[
x = \pm \frac{\sqrt{6}}{2}
\]
