Factorise: p2 + 6p - 16 – InterviewSolution

1.	Factorise: p2 + 6p - 16
Answer» First find the two numbers whose sum=6 and product= -16 Clearly, the numbers are 8 and 2 ∴ we get, p² +6p – 16 = p²+8p – 2p -16 = p (p+8) – 2(p+8) = (p+8) (p-2)

Factorise: p2 + 6p - 16

Answer»

First find the two numbers whose sum=6 and product= -16

Clearly, the numbers are 8 and 2

∴ we get, p² +6p – 16

= p²+8p – 2p -16

= p (p+8) – 2(p+8)

= (p+8) (p-2)
