Question

p²+6p-16
p²+6p+8
FACTORISE THESE

Answer 1

Answer:

Step-by-step explanation:

1) Let f (p) = p² + 6p - 16

= p² + 8p - 2p - 16 ( ∵ 8 × (-2) = - 16 ; 8- 2 = 6 )

= p ( p + 8 ) - 2 ( p + 8 )

= ( p - 2 ) ( p + 8 ) is the answer.

2) Let f (p) = p² + 6p + 8

= p² + 2p + 4p + 8 ( ∵ 2 × 4 = 8 : 2 + 4 = 6 )

= p ( p + 2 ) + 4 ( p + 2 )

= ( p + 2 ) ( p + 4 ) is the answer.
