Katia and Thomasina play a computer game and record these scores. Katia: 8, 6, -4, -7, 2, 0, 3 Thomasina: -11, 0, 8, 7, 5, -7, 11 Compare Katia's and Thomasina's least scores

Step-by-step explanation:

there is no factorization of y^2 -2y +35 in real numbers

Thomasina correctly determined two factors of 35 that differ by 2, but that is not what is needed here. For this problem, she needs two factors of 35 that have a sum of 2.* (There aren't any real-number factors that meet that condition.)

__

The factorization in complex numbers would be ...

 = (y -1 -i√34)(y -1 +i√34)

* Technically, she needs two factors of 35 with a sum of -2. Both factors would have to be negative.

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.
