when you multiply it with another polynomial
if you mean both dimensions are complex numbers, then you use foil. Example (1+i)(1+2i)= 1 + 3i - 2 (since i2 = -1) -1+3i that's a rectangle but you should understand if your in a class with complex #
Complex numbers are the square roots of negative numbers. i.e. root -1 = i
yes it does
Between Saran Wrap and foil, I would choose foil. But the best thing to use are freezer bags.
We should use it the same because it doesn't really affect our community
electrical engineers and quantum mechanics use them.
Yes, many
I suggest you read the Wikipedia article con complex numbers, specifically the section "Applications". One example is electrical engineering: in the case of AC, it helps to express all voltages, currents and impedances (equivalent of resistances) as complex numbers.
There are numerous applications; you should read the Wikipedia article on complex numbers for more examples. Some applications include: Get a better understanding of math. Even if you do calculations with real numbers, working with complex numbers often gives a greater understanding.Electricity, with AC, uses complex quantitites.Quantum physicsArt - ever seen the Mandelbrot set, or other fractals?There are numerous applications; you should read the Wikipedia article on complex numbers for more examples.

I'm not sure about how to use complex numbers to do this, but I've posted a link to a pretty neat website about Synthetic Division.
using contraction and expansion
Yes, you can use aluminum foil on the door of the oven, but it should be done with caution. Foil can reflect heat and may interfere with the oven's performance if it blocks vents. It's important to ensure that the foil is securely placed and does not touch any heating elements to avoid fire hazards. Always refer to your oven's manual for specific guidelines regarding the use of foil.
