Question

(x + y) (x - y) (x² + y²)
​

Answer 1

Answer:

(x^4 - y^4)

Step-by-step explanation:

(x + y) (x - y) (x² + y²)

= (x² - y²) (x² + y²)

= ((x²)² - (y²)²)

= (x^4 - y^4)

QUESTION :

(x + y) (x - y) (x² + y²)

SOLUTION :

➡ [ ( x + y ) ( x - y) ] ( x² + y² )

• It is in the form of (a + b) (a - b) = a² - b²

➡( x² - y² ) ( x² + y² )

• Again it is in the form of (a + b) (a - b) = a² - b²

➡ x⁴ - y⁴

Therefore, the value of(x + y) (x - y) (x² + y² ) = x⁴ - y⁴
