Use a special product pattern to evaluate I'm pretty sure I just normally solve it but I have no darn clue

240

Step-by-step explanation:

To evaluate 19^2 - 11^2, we have to use a special product pattern. Since this expression is in the form a^2 - b^2, we use the pattern (a + b)(a - b).

Therefore, the answer is 240.
