Quick help with Polynomial problem(not HW, just really confused on a problem)

Ok so i was looking through my book and i saw the problem

Write a polynomial function with zeroes -2 and 1+i, that also fits f(-2)=4

The zeroes should be -2 1+i and because 1+i is a complex number, another zero would be 1+i.

How could f(-2)=4 when -2 is a zero???

can anybody help me out with this?

I can help with programming and hardware.

I'm thinking maybe you can add more zeroes, but i just don't think it's possible, if while x is -2 y is zero, how could f(-2) = 4

I think there must be a mistake in the question

Don't ask to ask, just ask... please 🤨

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

does it mean maybe x-2 would be a zero, therefore f(2)=0??? idk its been awhile

no it said that a zero was -2, not a factor was x-2

The zeros would be x=-2 and x=1+i so rearrange them to equal zero, multiply them out and equate coefficients.

 

 

 

Edit: just realised that that is basically what you said in the post. Yep looks like the question is bust.
