Factor the expression over the complex numbers.

y^2+7

(y - i)(y + i)

Step-by-step explanation:

Factor as a difference of squares, that is

y² + 7

= y² - (i )²

= (y - i)(y + i)

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
