Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -0.3333333333 + 0.3333333333q + q2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + 0.3333333333q + 0.3333333333 + q2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + 0.3333333333q + q2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + 0.3333333333q + q2 = 0 + 0.3333333333 0.3333333333q + q2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 0.3333333333q + q2 = 0.3333333333 The q term is q. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.3333333333q + 0.25 + q2 = 0.3333333333 + 0.25 Reorder the terms: 0.25 + 0.3333333333q + q2 = 0.3333333333 + 0.25 Combine like terms: 0.3333333333 + 0.25 = 0.5833333333 0.25 + 0.3333333333q + q2 = 0.5833333333 Factor a perfect square on the left side: (q + 0.5)(q + 0.5) = 0.5833333333 Calculate the square root of the right side: 0.763762616 Break this problem into two subproblems by setting (q + 0.5) equal to 0.763762616 and -0.763762616.

Subproblem 1

q + 0.5 = 0.763762616 Simplifying q + 0.5 = 0.763762616 Reorder the terms: 0.5 + q = 0.763762616 Solving 0.5 + q = 0.763762616 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + q = 0.763762616 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + q = 0.763762616 + -0.5 q = 0.763762616 + -0.5 Combine like terms: 0.763762616 + -0.5 = 0.263762616 q = 0.263762616 Simplifying q = 0.263762616

Subproblem 2

q + 0.5 = -0.763762616 Simplifying q + 0.5 = -0.763762616 Reorder the terms: 0.5 + q = -0.763762616 Solving 0.5 + q = -0.763762616 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + q = -0.763762616 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + q = -0.763762616 + -0.5 q = -0.763762616 + -0.5 Combine like terms: -0.763762616 + -0.5 = -1.263762616 q = -1.263762616 Simplifying q = -1.263762616
