Factorise: p2 + 6p + 8

1.	Factorise: p2 + 6p + 8
Answer» First find the two numbers whose sum=6 and product= 8 Clearly, the numbers are 4 and 2 ∴ we get, p² +6p + 8 = p²+ 4p + 2p + 8 = p (p+4) + 2(p+4) = (p+2) (p+4)

Answer»

First find the two numbers whose sum=6 and product= 8

Clearly, the numbers are 4 and 2

∴ we get, p² +6p + 8

= p²+ 4p + 2p + 8

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

= (p+2) (p+4)
