Question

please answer fast 25x^3y - 121xy^3 factorise ​

Answer 1

Step-by-step explanation:

$25 {x}^{3} y - 121x {y}^{3} \\ \\ = xy(25 {x}^{2} - 121 {y}^{2} ) \\ \\ = xy( {5}^{2} {x}^{2} - {11}^{2} {y}^{2} ) \\ \\ = xy( {(5x)}^{2} - {(11y)}^{2} ) \\ \\ = xy(5x + 11)(5x - 11) \\ \\ formula \\ \\ {x}^{2} - {y}^{2} = (x + y)(x - y)$
