Question3. Multiply: $\frac{x^{2}-16}{x^{2}+4 x+4} \cdot \frac{x+2}{x-4}$

Studdy Solution
Cancel the common factors in the numerator and the denominator:
- Cancel $x - 4$ from the numerator and denominator. - Cancel one $x + 2$ from the numerator and denominator.
The simplified expression is:
$$\frac{x + 4}{x + 2}$$
The result of the multiplication is:
$$\boxed{\frac{x + 4}{x + 2}}$$
