Answer:
121x
Explanation:
= (-1 * 11 * x) * (-1 * 11) // We separate the -1, 11, and x from each term
= (-1 * -1) * (11 * 11) * x // Rearrange the terms
= 1 * 121 * x // -1 times -1 is 1, and 11 times 11 is 121
= 121x // Multiply 1 and 121 to get the final result
So, the product of -11x and -11 is 121x.
