Factorise the following expressions a. p^2+6p+8

(p+2) (p+4)

Step-by-step explanation:

Factor p2+6p+8

p2+6p+8

= (p+2) (p+4)

(p+4) (p+2)

Step-by-step explanation:

First because there is a p² we can put that in the brackets already.

(p) (p)

Then we need to find numbers that times together to give 8

8 4*2 8*1

So we only need one of these two pairs and to decide that we need to see which one adds/subtracts to form 6 (in the middle).

4-2=2 which is wrong4+2=6 which is correct

So 4 and 2 would go in the gaps:

(p+4) (p+2)
