Factor the expression over the complex numbers. x^2 +20 enter your answer in the box.

Step-by-step explanation:

Let solve this first:

Note: i = √-1

Using the property of radicals [√a√b=√(ab)], we can write √20 as:

√20 = √4√5 = 2√5

We can write:

x = ± 2√5 i

If we take the two roots (answers) as -a, and a, then we can write the factorization as:

(x - a ) (x + a)

Thus this factorization is:

b) well because you get well

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
