Subtract:
`5y^(2)` from `y^(2)`

Answer

To solve the problem of subtracting \( 5y^2 \) from \( y^2 \), we can follow these steps:

### Step 1: Identify the terms
We have two terms: \( y^2 \) and \( 5y^2 \).

### Step 2: Check if the terms are like terms
Both terms contain the variable \( y \) raised to the same power (which is 2). Therefore, they are like terms and can be combined.

### Step 3: Set up the subtraction
We need to subtract \( 5y^2 \) from \( y^2 \). This can be expressed as:
\[ y^2 - 5y^2 \]

### Step 4: Factor out the common term
Since both terms have \( y^2 \) in common, we can factor it out:
\[ y^2(1 - 5) \]

### Step 5: Simplify the expression
Now, simplify the expression inside the parentheses:
\[ 1 - 5 = -4 \]
So, we have:
\[ y^2(-4) = -4y^2 \]

### Final Answer
Thus, the result of subtracting \( 5y^2 \) from \( y^2 \) is:
\[ -4y^2 \]
