Question

express the product with the help of formula (49x×x×x×x-36y×y×y×y)​

Answer 1

Answer:

$(7 {x}^{2} - 6 {y}^{2} )(7 {x}^{2} + 6 {y}^{2} )$

Step-by-step explanation:

$49 {x}^{4} - 36 {y}^{4} = { 7{x}^{2} }^{2} - { 6{y}^{2} }^{2}$

$\implies(7 {x}^{2} - 6 {y}^{2} )(7 {x}^{2} + 6 {y}^{2} )$
