x=3 2/3
Suppose we have a generic polynomial of the form:

To know how many roots the polynomial can have, the first thing you should do is observe the term of greatest exponent.
For this case, the term of greatest exponent is 2.
Therefore, the polynomial has 2 roots.
Answer:
You must observe the term of the polynomial with greater exponent.
Answer:
<em>5,9,13,17,21</em>
Step-by-step explanation:
We can the values in "n"
a(1)=4(1)+1
a(1)=5
a(2)=4(2)+1
a(2)=9
a(3)=4(3)+1
a(3)=13
a(4)=4(4)+1
a(4)=17
a(5)=4(5)+1
a(5)=21
As you can see, each value consecutively increases by 4, this is also known as the common difference (d).
Answer:
2687
2687×100/59=4554.2
29×4554.2/100= 2686.97 aprox. 2687
