Factorise `x^(2)+6sqrt(6)x+48`.

Explanation

To factorise the expression \( x^2 + 6\sqrt{6}x + 48 \), we can follow these steps:

### Step 1: Rewrite the middle term
We start with the expression:
\[ x^2 + 6\sqrt{6}x + 48 \]
We can express \( 6\sqrt{6}x \) as a sum of two terms. We can choose \( 4\sqrt{6}x \) and \( 2\sqrt{6}x \) because \( 4 + 2 = 6 \):
