6x((x^(3))+7)^(2)-(6x^(2))((3x^(2))+5)((x^(3))+7)

To simplify the expression \( 6x \left( (x^3 + 7)^2 \right) - 6x^2 \left( (3x^2 + 5) \right) \left( (x^3 + 7) \right) \), we can proceed with step-by-step factoring and distribution.

### Expression: 
\[
6x \left( (x^3 + 7)^2 \right) - 6x^2 \left( (3x^2 + 5) \right) \left( (x^3 + 7) \right)
\]

#### Step 1: Factor out the common terms.
Both terms contain a common factor of \( 6x(x^3 + 7) \), so we can factor it out:

\[
6x(x^3 + 7) \left( (x^3 + 7) - x \cdot (3x^2 + 5) \right)
\]

#### Step 2: Simplify inside the parentheses.
Now, simplify the expression inside the parentheses:

\[
(x^3 + 7) - x(3x^2 + 5)
\]

Distribute \( x \) in the second part:

\[
(x^3 + 7) - (3x^3 + 5x)
\]

Now, combine like terms:

\[
(x^3 - 3x^3) + (7 - 5x) = -2x^3 + 7 - 5x
\]

#### Step 3: Substitute the simplified expression back:
Now substitute this result back into the factored form:

\[
6x(x^3 + 7) (-2x^3 + 7 - 5x)
\]

#### Final Expression:
Thus, the simplified expression is:

\[
6x(x^3 + 7)(-2x^3 + 7 - 5x)
\]

This is the factored form of the given expression.
