Question

Factorize each of the following:
a. x2 + 6x + 9​

Answer 1

Answer:

Hope it will helps U

Step-by-step explanation:

Look: (x + 3)2 = x2 + 6x + 9, and (x – 3)2 = x2 – 6x + 9! Here 9 can be written as (−3)2, so the middle term is 2(−3)x = −6x. So when the sign of the middle term is negative, the trinomial may be factored as (a – b)2.

Answer 2

Answer:

x2 + 6x + 9

x2 +3x+3x+9

x(x+3)+3(x+3)

(x+3)(x+3)

x=-3
