Which of the following are solutions to the equation below? check all that apply. 2x^2+5x+8=6 a. -2 b. -1 ] c. -1/2 d. 1/2 e. 1 f. 2

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
