What is the coefficient of `y xx (-3x^2)`?

Answer

To find the coefficient of the expression \( y \times (-3x^2) \), we can follow these steps:

### Step 1: Identify the expression
The expression we are working with is:
\[ y \times (-3x^2) \]

### Step 2: Simplify the expression
When we multiply \( y \) by \( -3x^2 \), we can rewrite the expression as:
\[ -3x^2y \]

### Step 3: Identify the coefficient
In the expression \( -3x^2y \), the coefficient is the numerical part that multiplies the variables. Here, the numerical part is:
\[ -3 \]

### Step 4: State the coefficient
Thus, the coefficient of the expression \( y \times (-3x^2) \) is:
\[ -3 \]

### Final Answer
The coefficient is \( -3 \).
