Question

x9y5-x5y9 factorise ​

Answer 1

${x}^{9} {y}^{5} - {x}^{5} {y}^{9} \\ \\ = {x}^{5} {y}^{5} ( {x}^{4} - {y}^{4} ) \\ \\ = {x}^{5} {y}^{5} (( { {x}^{2} })^{2} - { ({y}^{2} })^{2} ) \\ \\ = {x}^{5} {y}^{5} (( {x}^{2} + {y}^{2} )( {x}^{2} - {y}^{2} )) \\ \\ = {x}^{5} {y}^{5} ( {x}^{2} + {y}^{2})(x - y)(x + y)$

Thus FACTORIZED
