Answer 2

\[x^2 + 12x + 36 \implies x^2 + 6x + 6x + 36\]

Answer 3

i like to know how to factor it

Answer 4

its a perfect square right
(x+a)^2 = (x+a)(x+a) = x^2 +ax +ax+a^2
--> a^2 = 36 --> a = 6

Answer 5

I give you the example:

Suppose:

We are given with: \(x^2 + 2x + 2x + 4\)

So,
group the terms first:

\((x^2 + 2x) + (2x + 4)\)

= \(x(x+2) + 2(x+2)\)

So, \((x+2)(x+2)\)

Answer 6

In place of 2 there is 6 and in place of 4 there is 36..
