Question

(x square- y square)(x square +y square)+(y square-z square)( y square +z square ) in suitable property ​

Answer 1

(x² - y²) (x² + y²) + (y² - z²) (y² + z²)

(x⁴ - y⁴) + (y⁴ - z⁴)

= (x⁴ - z⁴)

= (x² + z²) (x² - z²)

Answer 2

Answer:

Step-by-step explanation:

(x²-y²)(x²+y²)+(y²-z²)(y²+z²)

we can solve it by using the formula (a-b)(a+b)

((x²)²-(y²)²)+((y²)²-(z²)²)

(x⁴-y⁴)+(y⁴-z⁴)

x⁴-y⁴+y⁴-z⁴

x⁴-z⁴
