Simplify the following using brackets.
`36 xx 48`

Answer

To simplify the expression \( 36 \times 48 \) using brackets, we can follow these steps:

### Step-by-Step Solution:

1. **Rewrite the Numbers**:
We can express 36 and 48 in terms of a common number. Let's write:
\[ 36 = 50 - 14 \quad \text{and} \quad 48 = 50 - 2 \]
So, we can rewrite the expression as:
\[ 36 \times 48 = (50 - 14) \times (50 - 2) \]

2. **Use the Formula**:
We can use the formula for the product of two binomials, which is:
\[ (x - a)(x - b) = x^2 - (a + b)x + ab \]
Here, \( x = 50 \), \( a = 14 \), and \( b = 2 \).

3. **Substitute Values into the Formula**:
Now we substitute the values into the formula:
\[ (50 - 14)(50 - 2) = 50^2 - (14 + 2) \times 50 + (14 \times 2) \]

4. **Calculate Each Part**:
- Calculate \( 50^2 \):
\[ 50^2 = 2500 \]
- Calculate \( a + b \):
\[ 14 + 2 = 16 \]
- Calculate \( ab \):
\[ 14 \times 2 = 28 \]

5. **Combine the Results**:
Now, substitute these values back into the expression:
\[ 2500 - 16 \times 50 + 28 \]
- Calculate \( 16 \times 50 \):
\[ 16 \times 50 = 800 \]
- Now substitute this back:
\[ 2500 - 800 + 28 \]

6. **Final Calculation**:
- First, subtract \( 800 \) from \( 2500 \):
\[ 2500 - 800 = 1700 \]
- Then, add \( 28 \):
\[ 1700 + 28 = 1728 \]

### Final Answer:
Thus, the simplified result of \( 36 \times 48 \) is:
\[ \boxed{1728} \]
