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.

Answer:
<em>4.42 ounces </em>
Step-by-step explanation:
Given:
The solid food Stacie has eaten in the noon meal:
1. of a 3-ounce serving of meatloaf.
2. of her 3-ounce serving of mashed potatoes
3. of a 2-ounce serving of green beans
To find:
How many ounces of solid food was consumed by Stacie (upto 2 decimal places) ?
Solution:
Let us convert the given fractions to decimal form upto 2 decimal places:
1. meatloaf .
2. mashed potatoes .
3. green beans.
Let us add the above 3 quantities to get total solid food consumed.
Total solid food consumed = 1.50 + 2.25 +0.67 = <em>4.42 ounces.</em>

So, the answer is <em>4.42 ounces.</em>
