Hello,
1) order the terms:
3x^3+6x^2+5x+10
2) method: grouping 2 to 2 the terms:
=(3x^3+6x^2)+(5x+10)
=3x^2(x+2)+5(x+2)=(x+2)(3x^2+5)
Answer:
1)
=0.3571428571 2) Terminating
Step-by-step explanation:
1st. To answer this question let's divide with long division algorithm 5 and -14.

5 (dividend) : -14 (divisor) 
Long division (check below)
With the same two numbers -14 and 5 we can write in a Long Division
5) -14
<u> - 2.8</u>
5) -14
10
40
So 
2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.
form.

Answer:
<h2>z = 27°</h2>
Because that angle is 30°.
it's nearest value is 27.
