Expression Simplification 9Cc8C2
1. **State the problem:** Simplify the expression $$\frac{2y - 2x \times \frac{2x}{y}}{y}$$.
2. **Recall the order of operations:** Multiplication and division are performed before addition and subtraction.
3. **Rewrite the expression clearly:** $$\frac{2y - 2x \cdot \frac{2x}{y}}{y}$$.
4. **Multiply inside the numerator:** Multiply $2x$ by $\frac{2x}{y}$:
$$2x \times \frac{2x}{y} = \frac{4x^2}{y}$$.
5. **Substitute back into numerator:**
$$2y - \frac{4x^2}{y}$$.
6. **Find common denominator in numerator:** To combine terms, write $2y$ as $\frac{2y^2}{y}$:
$$\frac{2y^2}{y} - \frac{4x^2}{y} = \frac{2y^2 - 4x^2}{y}$$.
7. **Rewrite the entire expression:**
$$\frac{\frac{2y^2 - 4x^2}{y}}{y} = \frac{2y^2 - 4x^2}{y \cdot y} = \frac{2y^2 - 4x^2}{y^2}$$.
8. **Factor numerator:**
$$2y^2 - 4x^2 = 2(y^2 - 2x^2)$$.
9. **Final simplified expression:**
$$\frac{2(y^2 - 2x^2)}{y^2}$$.
This is the simplified form of the original expression.
