Question

the factors of x^4 + 625​

Answer 1

Correct Question :

➨ Factors of x⁴ - 625

Solution :

x⁴ can be written as ( x² )²

625 can be written as ( 25 )²

Now

➨ ( x² )² - ( 25 )²

By using identity :

➨ a² - b² = ( a + b ) ( a - b )

➨ ( x² + 25 ) ( x² - 25 )

Again by using a² - b²

➨ ( x² + 25 ) ( x + 5 ) ( x - 5 )
