Both A and C would be solutions to the equation.
In order to solve for this you must first get the equation equal to 0.
2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)
Now we can plug these values into the quadratic equation.





or -1/2 for the first answer

or -2 for the second answer
I think 7 oranges for $2.45 are better.
Answer:
3/110
Step-by-step explanation:
x = .0272727 repeating
Multiply by 100
100x = 2.727 repeating
Subtract the first equation from the second
100x = 2.727 repeating
-x = .0272727 repeating
------------------------------------
99x = 2.7
Divide each side by 99
99x/99 = 2.7/99
x = 27/990
x =3/110
