x =
Solution
To solve the quadratic equation 3x^2 + 6x + 2 = 0, we can use the quadratic formula, which is x = [-b ± sqrt(b^2 - 4ac)] / (2a).
Here, a = 3, b = 6, and c = 2.
Step 1: Calculate the discriminant (b^2 - 4ac) Discriminant = (6)^2 - 432 = 36 - 24 = 12
Step 2: Substitute a, b, and the discriminant into the quadratic formula x = [-6 ± sqrt(12)] / (2*3) x = [-6 ± 2sqrt(3)] / 6
Step 3: Simplify the expression x = -1 ± sqrt(3)/3
So, the solutions to the equation 3x^2 + 6x + 2 = 0 are x = -1 + sqrt(3)/3 and x = -1 - sqrt(3)/3.
