Question

factorisation of (y^3 - 8)​

Answer 1

hey your answer is above

Answer 2

Answer:-

(y - 2)(y² + 2y + 4)

Step-by-step explanation:-

As we know,

• a³ - b³ = (a -b)(a² + ab +b²)

y³ - 8

⇒ (y)³ - (2)³

• Here, a = y and b = 2

⇒ (y - 2)(y² + 2y + 4)

Answer⇒ (y - 2)(y² + 2y + 4)

I hope that this helped you :-)
