Question

a⁴+2a²b²+b⁴
(x+y)⁴-(x-y)⁴​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

${[(x + y) ^{2} ]}^{2} - {[(x - y) ^{2} ]}^{2}$

$\boxed{ \blue{{a}^{2} - {b}^{2} = (a + b)(a - b)}}$

$\implies[(x + y) ^{2} + (x - y) ^{2} ] [(x + y) ^{2} - (x - y) ^{2} ]$

$\implies[(x ^{2} + 2xy + y ^{2} ) + (x ^{2} - 2xy + y ^{2} ) ] [(x + y + x - y) (x + y - x + y) ]$

$\implies[2x ^{2} + 2y ^{2} ] [(2x ) ( 2y ) ]$

$\implies[2x ^{2} + 2y ^{2} ] [4xy]$

$\orange{\therefore8x ^{3} y + 8y ^{3}x }$
