We are given the following expression to multiply and simplify:

\[
\frac{(x^2 + x - 2)(xy^2)}{(x^2 + 4x + 4)(x^7y)}
\]

### Step 1: Factor the quadratic expressions
First, let's factor the quadratic expressions in the numerator and the denominator.

- \( x^2 + x - 2 \) factors as \( (x + 2)(x - 1) \)
- \( x^2 + 4x + 4 \) factors as \( (x + 2)(x + 2) \) or \( (x + 2)^2 \)

Now, we rewrite the expression using the factored forms:

\[
\frac{(x + 2)(x - 1)(xy^2)}{(x + 2)^2(x^7y)}
\]

### Step 2: Simplify by canceling common factors
We see that there is a common factor of \( x + 2 \) in both the numerator and denominator. Cancel one \( x + 2 \) from both:

\[
\frac{(x - 1)(xy^2)}{(x + 2)(x^7y)}
\]

### Step 3: Combine like terms
Now, let's simplify the remaining expression by multiplying and canceling terms.

- Numerator: \( (x - 1)(xy^2) = x(x - 1)y^2 \)
- Denominator: \( (x + 2)(x^7y) = x^7(x + 2)y \)

Now the expression becomes:

\[
\frac{x(x - 1)y^2}{x^7(x + 2)y}
\]

### Step 4: Simplify the powers of \( x \) and \( y \)
- \( \frac{x}{x^7} = \frac{1}{x^6} \)
- \( \frac{y^2}{y} = y \)

Thus, the simplified expression is:

\[
\frac{(x - 1)y}{x^6(x + 2)}
\]

### Final Answer:
The simplified expression is:

\[
\frac{(x - 1)y}{x^6(x + 2)}
\]
