E=3x6x6
e=3x36
e=108
hope it helps
4x + 1 = x^2 + 3x - 1
4x = x^2 + 3x - 2
0 = x^2 -x - 2
0 = x^2 -x + 1 - 3
0 = (x - 1)^2 - 3
3 = (x - 1)^2
sqrt 3=(x-1) and (-(x-1))
x = 1+sqrt 3 and 1-sqrt 3
sqrt means square root

Answer:

Step-by-step explanation:
To factorize, at first, do factorize all the terms then take the common terms out.
(a) 
This can be written as

Now, taking x commom from both the terms.

(b) 

Now, taking
common from both the terms, we have

This is the required factorization.
(c) 

This is the required factorization.
(d) 

This is the required factorization.
