-27=2x^2-4 PLEASE HELP ASAP

and complex solutions:  

Step-by-step explanation:

-27 = 2x² - 4

-2x² = 27 - 4

-2x² = 23

 x² = -23/2

means NO REAL SOLUTIONS  

(as there is no real number that put instead of x gives value less then 0)

However in complex numbers we have:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
