Factorize each of the following expressions:\(\frac{50}{x^2}-\frac{2x^

1.	Factorize each of the following expressions:\(\frac{50}{x^2}-\frac{2x^2}{81}\)
Answer» \(2(\frac{25}{x\times x}-\frac{x\times x}{81})\) = \(2[(\frac{5}{x})^2-(\frac{x}{9})^2]\) = \(2[(\frac{5}{x}+\frac{x}{9})(\frac{5}{x}-\frac{x}{9})\)

Factorize each of the following expressions:\(\frac{50}{x^2}-\frac{2x^2}{81}\)

Answer»

\(2(\frac{25}{x\times x}-\frac{x\times x}{81})\)

= \(2[(\frac{5}{x})^2-(\frac{x}{9})^2]\)

= \(2[(\frac{5}{x}+\frac{x}{9})(\frac{5}{x}-\frac{x}{9})\)
