Decide among the following sets, which are subsets of which: `A={x : x` satisfies `x^2-8x+12=0},\ B={2,4,6},\ C={2,4,6,8 },\ D={6}dot`

Explanation

To determine which sets are subsets of which among the given sets \( A, B, C, \) and \( D \), we will first need to find the elements of set \( A \) based on the quadratic equation provided.

### Step 1: Solve the quadratic equation for set \( A \)

The equation given is:
\[ x^2 - 8x + 12 = 0 \]
