Solve this quadratic equation using the quadratic formula.
dybincka [34]
Solve for x over the real numbers:
3 x^2 + 5 x + 1 = 0

Divide both sides by 3:
x^2 + (5 x)/3 + 1/3 = 0

Subtract 1/3 from both sides:
x^2 + (5 x)/3 = -1/3

Add 25/36 to both sides:
x^2 + (5 x)/3 + 25/36 = 13/36

Write the left hand side as a square:
(x + 5/6)^2 = 13/36

Take the square root of both sides:
x + 5/6 = sqrt(13)/6 or x + 5/6 = -sqrt(13)/6

Subtract 5/6 from both sides:
x = sqrt(13)/6 - 5/6 or x + 5/6 = -sqrt(13)/6

Subtract 5/6 from both sides:

Answer: x = sqrt(13)/6 - 5/6 or x = -5/6 - sqrt(13)/6

Leona [35]

Answer:

The answer is 16 hours

Step-by-step explanation:

The Reason why it is 16 hours is simply because it says in the question  

"The moon is around 239,000 miles from Earth. How many hours would it take a rocket that can travel at 250 MILES PER MINUTE to travel to the moon? Round to the nearest hour. "

So, turn 16 hours into minutes, 16 X 60 = 960 X 250 miles per min = 240,000, miles there you go! the answer is B!
