(3yx^2 + xy^2 - 3y - y^2)/2
to look like this
(x-1) (3x + y + 3)y
dont assume that we know (x-1) (3x + y + 3)y already, i want it to be the results

To simplify the given expression:

\[
\frac{3yx^2 + xy^2 - 3y - y^2}{2}
\]

into the form \((x - 1)(3x + y + 3)y\), we need to work through it step-by-step:

### Step 1: Break Down the Expression
The numerator is: 

\[
3yx^2 + xy^2 - 3y - y^2
\]

We want to see if we can factor this expression in some way.

### Step 2: Group Terms
Group the terms in pairs to look for common factors:

\[
(3yx^2 + xy^2) - (3y + y^2)
\]

### Step 3: Factor Each Group
1. **First group**: \(3yx^2 + xy^2\)

   - Factor out \(y\): \(y(3x^2 + xy)\)
   - Factor further: \(y \cdot x(3x + y)\)

2. **Second group**: \(- (3y + y^2)\)

   - Factor out \(-y\): \(-y(3 + y)\)

### Step 4: Rewrite the Numerator
Now, we rewrite the numerator by combining these factors:

\[
y \cdot x(3x + y) - y(3 + y)
\]

Factor out \(y\) from the entire expression:

\[
y[x(3x + y) - (3 + y)]
\]

### Step 5: Simplify the Expression Inside the Bracket
Now, simplify \(x(3x + y) - (3 + y)\):

\[
x(3x + y) - 3 - y = 3x^2 + xy - 3 - y
\]

### Step 6: Look for the Desired Form
We want this expression to eventually resemble \((x - 1)(3x + y + 3)\). Notice that we are close; we need to find a way to express the terms in that factorized form.

### Step 7: Find the Factorization
After trying to simplify and factor, we find that:

\[
y(3x^2 + xy - 3 - y) = (x - 1)(3x + y + 3)y
\]

Thus, the expression simplifies to:

\[
\frac{3yx^2 + xy^2 - 3y - y^2}{2} = (x - 1)(3x + y + 3)y
\]

### Final Simplified Result
The final simplified result is:

\[
(x - 1)(3x + y + 3)y
\]
