Solution Steps
To solve the quadratic equation using the zero-factor property, we need to:
Move all terms to one side of the equation to set it to zero.
Factor the quadratic expression.
Set each factor equal to zero and solve for \( x \).
Solution Approach
Rewrite the equation in standard form: \( 9x^2 - 22x + 8 = 0 \).
Factor the quadratic expression.
Solve for \( x \) by setting each factor to zero.
Step 1: Rewrite the Equation
We start with the given equation:
\[
9x^2 = 22x - 8
\]
Rearranging it to standard form gives:
\[
9x^2 - 22x + 8 = 0
\]
Step 2: Factor the Quadratic
Next, we factor the quadratic expression \( 9x^2 - 22x + 8 \). The factors of this expression are:
\[
(9x - 2)(x - 4) = 0
\]
Step 3: Solve for \( x \)
Using the zero-factor property, we set each factor equal to zero:
\( 9x - 2 = 0 \) leads to \( x = \frac{2}{9} \)
\( x - 4 = 0 \) leads to \( x = 4 \)
Final Answer
The solution set is:
\[
\boxed{\left\{ \frac{2}{9}, 4 \right\}}
\]
