Question

factorise the following expression.
$\frac{9}{64} x ^{2} - \frac{1}{144} y {}^{2}$
​

Answer 1

Answer:

$\frac{9}{64} {x}^{2} - \frac{1}{144} {y}^{2} \\ { (\frac{3}{8} x)}^{2} - {( \frac{1}{12} y)}^{2} \\ \\ {a}^{2} - {b}^{2} = (a + b )(a - b) \\ \\ ( \frac{3}{8} x + \frac{1}{12} y)( \frac{3}{8} x - \frac{1}{12} y)$
