Question

the product of (x+y) (x-y) (x^+y^) is ?

Answer 1

Answer:

Step-by-step explanation:

(x+y)(x-y)(x^2+y^2)

(x^2-y^2)(x^2+y^2)

x^4-y^4

Answer 2

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

Identity used

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

Hope it helpss
