Factor the polynomial x^4-16. How many real zeros does the function g(x)=x^4-16 have?

Answer:(x-2)(x+2)(x^2 + 4)Step-by-step explanation:This can be done by difference of squares:(x^2 - 4) (x^2 + 4) And now (x^2 - 4) can be further factored:(x-2)(x+2)(x^2 + 4) is your answerClearly, There are only 2 zeroes that we can get from this, 2 and -2Hope this helps!If you think I helped please mark brainliest! Would really appreciate!
