Thanks x^2 you are absolutely correct :)

But sometimes the letter i is used as the basic unit of the comples (imaginary) number system.

If i is the imaginary number then  $$i=\sqrt{-1}$$

Then

$$6i^2-2i\\ =6*-1-2i\\ =-6-2i$$

SImplifying this should be relatively simple.

 $$-2i(4-3i)+6i$$ Distribute the -2i into the parentheses $$-8i+6i^2+6i$$ Combine the like terms $$-2i+6i^2$$ Rearrange the terms so the term with the highest degree is first $$6i^2-2i$$ You are done!
