Question

factorize give answer fast please

Answer 1

Step-by-step explanation:

$= 256 {x}^{4} - {x}^{2} {y}^{2} + 49 {y}^{4} \\ = ( {16 {x}^{2}) }^{2} + ( {7 {y}^{2} )}^{2} + 2(16 {x}^{2} )(7 {y}^{2} ) - 2(16 {x}^{2} )(7 {y}^{2} ) - {x}^{2} {y}^{2} \\ = (16{ {x}^{2} + 7 {y}^{2} })^{2} - 224 {x}^{2} {y}^{2} - {x}^{2} {y}^{2} \\ = (16{ {x}^{2} + 7 {y}^{2} })^{2} - 225 {x}^{2} {y}^{2} \\ = (16{ {x}^{2} + 7 {y}^{2} })^{2} - ( {15xy)}^{2} \\ = (16{ {x}^{2} + 7 {y}^{2} } - 15xy)(16{ {x}^{2} + 7y}^{2} + 15xy)$
