6x(3x+1)³-(3x+1)⁴ factor it using any factoring techniques 

To factor the expression \( 6x(3x + 1)^3 - (3x + 1)^4 \), let's follow these steps:

### Step 1: Identify the common factor
The expression can be rewritten as:
\[
6x(3x + 1)^3 - 1 \cdot (3x + 1)^4
\]

Here, \( (3x + 1)^3 \) is a common factor. Let's factor it out:
\[
(3x + 1)^3 \cdot \left[ 6x - (3x + 1) \right]
\]

### Step 2: Simplify the expression in the brackets
Simplify the expression inside the brackets:
\[
6x - (3x + 1) = 6x - 3x - 1 = 3x - 1
\]

### Step 3: Write the fully factored form
Now, substituting back, the factored form of the expression is:
\[
(3x + 1)^3 \cdot (3x - 1)
\]

Thus, the factored form of the expression \( 6x(3x + 1)^3 - (3x + 1)^4 \) is:
\[
\boxed{(3x + 1)^3 \cdot (3x - 1)}
\]
