Find theproduct using suitable identity (a+3) (a-3 )( a square +9)

1.	Find theproduct using suitable identity (a+3) (a-3 )( a square +9)
Answer» (a+3)(a-3)(a²+9) = (a²-3²)(a²+9) USING (a+b)(a-b)=a²-b² = (a²-9)(a²+9) = ((a²)²-9²) Using (a+b)(a-b)=a²-b² = (a²×²-81) = (a RAISE to the POWER 4-81) HOPE YOU ARE SATISFIED

Answer»

(a+3)(a-3)(a²+9)

= (a²-3²)(a²+9) USING (a+b)(a-b)=a²-b²

= (a²-9)(a²+9)

= ((a²)²-9²) Using (a+b)(a-b)=a²-b²

= (a²×²-81)

= (a RAISE to the POWER 4-81)

HOPE YOU ARE SATISFIED
