Solve 3x2 + 2x + 7 = 0. Round solutions to the nearest hundredth.

(A) x ≈ - 1.90 and x ≈ 1.23

(B) x ≈ - 1.23 and x ≈ 1.90

(C) x ≈ - 0.44 and x ≈ - 3.56

(D) No real solutions

The answer in the problem above is written in the equation below where the answer is (x + 1/9) ^2 = - 20/9 or letter B. x = - 1.23.

3x^2 + 2x + 7 = 0

3 (x^2 + 2x/3 + 7/3) = 0

x^2 + 2x/3 + 1/9 = - 7/3 + 1/9

(x + 1/9) ^2 = - 20/9
