Find the product.(x – 3)(x + 3) (x2 + 9)

1.	Find the product.(x – 3)(x + 3) (x2 + 9)
Answer» (x – 3)(x + 3) (x² + 9) Identity(a + b)(a-b) = a² – b² = (x² – 3²)(x² + 9) = (x² – 9)(x² + 9) = (x²)²– 9² = x⁴ – 81

Answer»

(x – 3)(x + 3) (x² + 9)

Identity(a + b)(a-b) = a² – b²

= (x² – 3²)(x² + 9)

= (x² – 9)(x² + 9)

= (x²)²– 9²

= x⁴ – 81
