Let's solve the expression $2 \times 2 \times 6^2 - 2^2$.

1. First, calculate $6^2$: $6^2 = 36$

2. Multiply $2 \times 2 \times 36$: $2 \times 2 = 4$ $4 \times 36 = 144$

3. Then, calculate $2^2$: $2^2 = 4$

4. Finally, subtract $2^2$ from the previous result: $144 - 4 = 140$

The result of the expression $2 \times 2 \times 6^2 - 2^2$ is 140.
