Question

factories:y^4-625 anewer me plzz​

Answer 1

Step-by-step explanation:

(y²)²-(25)²=(y²-25)(y²-25).

=(y+5) (y-5)(y²+25)

Answer 2

Answer:

(y² + 25) ( y + 5 ) ( y - 5 )

Step-by-step explanation:

Using identity a² - b² = ( a + b) ( a - b)

$625 = ( {25}^{2}) {}^{} \\ y {}^{4} = ( {y}^{2} ) {}^{2} \\ ((y {}^{2}) {}^{2} - 25 {}^{2} ) = ( {y}^{2} + 25)( {y}^{2} - 25) \\ = ( {y}^{2} + 25)(y + 5)(y - 5)$

I am sure about my answer friend!

Hope my answer helps you buddy!

Have a great day ahead!
