To solve an equation by completing the square, let's go through the general process step by step. If you provide me with the equation, I'll walk through the solution.

Here's a general overview of the process of completing the square for a quadratic equation:

Given:

$ax^2 + bx + c = 0$

1. Divide by 'a' (if $a \neq 1$):
   Make the coefficient of $x^2$ equal to 1 by dividing the entire equation by $a$. $x^2 + \frac{b}{a}x + \frac{c}{a} = 0$

2. Move the constant term to the other side: $x^2 + \frac{b}{a}x = -\frac{c}{a}$

3. Complete the square:
   Take half the coefficient of $x$, square it, and add it to both sides. [
