Answer:
x = -1±sqrt(5/3)
Step-by-step explanation:
3x^2+6x=2
We will use completing the square
Factor out a 3 on the left
3(x^2 +2x) = 2
Divide each side by 3
3/3(x^2 +2x) = 2/3
(x^2 +2x) = 2/3
2/2 = 1 1^2 =1
Add 1 to each side
(x^2 +2x+1) = 2/3+1
(x+1) ^2 = 2/3 +3/3
(x+1)^2 = 5/3
Take the square root of each side
sqrt((x+1)^2) = ±sqrt(5/3)
x+1 = ±sqrt(5/3)
Subtract 1 from each side
x+1-1 = -1±sqrt(5/3)
x = -1±sqrt(5/3)
Answer:
0.75 (75%) of a bag
Step-by-step explanation:
The question states that Frank has 3 bags and 4 bird feeders. In order to know how much of the bags he needs to add to each feeder, we are going to need to divide the amount of bags by the amount of feeders. This in term will give us an equal amount that should be added to each feeder. ... simplify We see from the calculation above that each feeder will get an equal amount of 0.75 (75%) of a bag.
