Question

Factorise
b2 + 5b + 6

Answer 1

(b + 2) (b + 3)

Explanation:

b² + 5b + 6

Known :

a = 1

b = 5

c = 6

Asked :

Factorise b² + 5b + 6 = ...?

Answer :

p × q = c

p + q = b

So :

p × q = 6

2 × 3 = 6

p + q = 5

2 + 3 = 5

So, p = 2 & q = 3

So, factorise b² + 5b + 6 is (b + 2) (b + 3)

Hope it helpful and useful :)

Answer 2

Explanation:

Step 1: Factor

`b^2 + 5b + 6`

`b^2 + 3b + 2b + 6`

`(b + 3)(b + 2)`

Answer:
`(b + 3)(b + 2)`
