To solve the quadratic equation 3x^2 + 5x + 2 = 0 using the quadratic formula, we have:

a = 3, b = 5, c = 2

The quadratic formula is given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Substituting the values:

x = (-(5) ± sqrt(5^2 - 4(3)(2))) / 2(3)

x = (-5 ± sqrt(25 - 24)) / 6

x = (-5 ± sqrt1) / 6

Now, we have two solutions:

x = (-5 + 1) / 6 = -4/6 = -2/3

x = (-5 - 1) / 6 = -6/6 = -1

So the correct answer is: x = -2/3, -1.

a = 3, b = 5, c = 2

The quadratic formula is given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Substituting the values:

x = (-(5) ± sqrt(5^2 - 4(3)(2))) / 2(3)

x = (-5 ± sqrt(25 - 24)) / 6

x = (-5 ± sqrt1) / 6

Now, we have two solutions:

x = (-5 + 1) / 6 = -4/6 = -2/3

x = (-5 - 1) / 6 = -6/6 = -1

So the correct answer is: x = -2/3, -1.
