ALGEBRA!!
Factor completely over the complex numbers.
x^4+18x^2+81
Any idea how the final answer looked like?
(x^2+9)(x^2+9)

Best ResponseYou've already chosen the best response.0Yep maybe (x^2+9i)^2 (x^2+9i)^2 ?

Best ResponseYou've already chosen the best response.2fill in the blanks x^2 + 9 = (x 3i)(x 3i) ?

Best ResponseYou've already chosen the best response.0x^4+18x^2+81 this is the that will be factored over the complex numbers

Best ResponseYou've already chosen the best response.2so complete factors are (x + 3i)(x  3i)(x + 3i)(x  3i))

Best ResponseYou've already chosen the best response.0Is that the same with (x+3i)^2(x3i)^2 ??

Best ResponseYou've already chosen the best response.2yes you can write it that way

Best ResponseYou've already chosen the best response.2are you happy about multiplying these imaginary numbers? 3i * + 3i = 9 * i^2 = 9 *  1 = +9 because i^2 = 1

Best ResponseYou've already chosen the best response.2If you expanded that the first term would be x^8 not x^4
