Question

simplify by using algebraic identities:(x+y)(x-y)(x^2+y^2)​

Answer 1

Answer:

Step-by-step explanation:

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

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

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

x^4-y^4

Answer 2

Answer:

Given : (x + y) (x - y) (x² + y²)

U can write this as :

(x² - y²) (x² + y ²)

= By using formula: (a + b) (a - b) = ( a²-b²)

we get (x² - y²) (x² + y²)

= (x²)² - (y²)²

= x⁴ - y⁴ ( Answer)
