Answer:
Fourth degree polynomial (aka: quartic)
====================================================
Work Shown:
There isnt much work to show here because we can use the fundamental theorem of algebra. The fundamental theorem of algebra states that the number of roots is directly equal to the degree. So if we have 4 roots, then the degree is 4. This is assuming that there are no complex or imaginary roots.
-------------------
If you want to show more work, then you would effectively expand out the polynomial
(x-m)(x-n)(x-p)(x-q)
where
m = 4, n = 2, p = sqrt(2), q = -sqrt(2)
are the four roots in question
(x-m)(x-n)(x-p)(x-q)
(x-4)(x-2)(x-sqrt(2))(x-(-sqrt(2)))
(x-4)(x-2)(x-sqrt(2))(x+sqrt(2))
(x^2-6x+8)(x^2 - 2)
(x^2-2)(x^2-6x+8)
x^2(x^2-6x+8) - 2(x^2-6x+8)
x^4-6x^3+8x^2 - 2x^2 + 12x - 16
x^4 - 6x^3 + 6x^2 + 12x - 16
We end up with a 4th degree polynomial since the largest exponent is 4.
You do 168+21=189 then you work out what 189 is as % so your answer =18900%
Answer:
1. d = -6 2. n = -80
Step-by-step explanation:
If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!
