Which Expression Is Equivalent To This Polynomial X2 12 class=

Sagot :

Answer:

Option A is the correct answer

A. [tex](x+2\sqrt3 i)(x-2\sqrt3 i)[/tex]

Step-by-step explanation:

[tex](x + 2 \sqrt{3} i)(x - 2 \sqrt{3} i) \\ \\ = {(x)}^{2} - (2 \sqrt{3} i)^{2} \\ \\ = {x}^{2} - {(2)}^{2} {( \sqrt{3} )}^{2} {i}^{2} \\ \\ = {x}^{2} -12 {i}^{2} \\ \\ = {x}^{2} - 12( - 1) \\ (\because i^2=-1) \\ = {x}^{2} + 12[/tex]
