Difference of squares gives which complex factors for the expression x^2+13 a. (x - i sqr 13)(x - i sqr 13) b. (x + 13i)^2(x - 13i)^2 c.(x + i sqr 13)(x - i sqr 13) d. (x + 13i)(x - 13i) asap pls

Option C.

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

             = x² + [-(i)²√(13)²]  [Since i = √(-1)]

             = x² - (i√13)²

             = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]

Option C will be the answer.

ik how do do this just give me a few minutes and i will give it to

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
