Hey can you me posted picture of question

The solutions are 8 and -8

Explanation:
Before we begin, remember the rule of the difference between squares which is as follows:
x² - a² = (x+a)(x-a)

Now, for the given, we have:
x² - 64 = 0
This is equivalent to:
x² - (8)² = 0

Applying the rule of the difference between squares mentioned above, we would factorize the equation as follows:
(x-8)(x+8) = 0
This means that:
either x-8 = 0 > x = 8
or x+8 = 0 > x = -8

Based on the above, the solutions would be: 8 and -8

Hope this helps :)

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
