You know 1 is not a root because the sum of the coeffcients of the equation is 14, not zero.
It is fairly easy to try 3 by synthetic division (see attachment), which tells you that 3 is a root and the remaining quadratic factor is x²-3x-5. The quadratic formula tells you the roots of that factor are
... x = (-b±√(b²-4ac))/(2a) = (3±√29)/2
The appropriate choices are
... C. (3-√29)/2
... D. (3+√29)/2
... F. 3
_____
The quadratic formula tells you the solution to
... ax²+bx+c=0
is x = (-b±√(b²-4ac))/(2a)
We have a=1, b=-3, c=-5.

The 3rd one because when you find the absolute value of a number, it will always be positive. So the list would be 3.5, 4.2, 9
x = 2
Step-by-step explanation:
3(x + 1) - 2 = x + 5
3x + 3 - 2 = x + 5
3x + 1 = x + 5
3x - x = 5 - 1
2x = 4
x = 4 / 2
x = 2
When exchanging from your currency to another country's currency using a foreign exchange table, you should <span>multiply the amount you have by the exchange rate. The correct option among all the options that are given in the question is the first option. I hope that this answer has come to your help.</span>
