Factorize each of the following expressions:\(\frac{1}{16}x^2y^2 - \fr

1.	Factorize each of the following expressions:\(\frac{1}{16}x^2y^2 - \frac{4}{49}y^2z^2\)
Answer» \((\frac{1}{4}xy)^2 - (\frac{2}{7}yz)^2\) = \((\frac{xy}{4}+\frac{2yz}{7})(\frac{xy}{4}-\frac{2yz}{7})\) = \(y^2(\frac{x}{4}+\frac{2}{7}z)(\frac{x}{4}-\frac{2}{7}z)\)

Factorize each of the following expressions:\(\frac{1}{16}x^2y^2 - \frac{4}{49}y^2z^2\)

Answer»

\((\frac{1}{4}xy)^2 - (\frac{2}{7}yz)^2\)

= \((\frac{xy}{4}+\frac{2yz}{7})(\frac{xy}{4}-\frac{2yz}{7})\)

= \(y^2(\frac{x}{4}+\frac{2}{7}z)(\frac{x}{4}-\frac{2}{7}z)\)
