Find the product.(P + 2) (P – 2) (P2 + 4)

1.	Find the product.(P + 2) (P – 2) (P2 + 4)
Answer» (P + 2) (P – 2) (P² + 4) Identity (a + b)(a – b) = a² – b² = (P² – 2²)(P²+ 4) = (P² – 4)(P² + 4) = (P²)² – 4² = P⁴ – 16

Answer»

(P + 2) (P – 2) (P² + 4)

Identity (a + b)(a – b) = a² – b²

= (P² – 2²)(P²+ 4)

= (P² – 4)(P² + 4)

= (P²)² – 4²

= P⁴ – 16
