Simplifying 14 + -1q = 2q2 Solving 14 + -1q = 2q2 Solving for variable 'q'. Combine like terms: 2q2 + -2q2 = 0 14 + -1q + -2q2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -7 + 0.5q + q2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 0.5q + 7 + q2 = 0 + 7 Reorder the terms: -7 + 7 + 0.5q + q2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 0.5q + q2 = 0 + 7 0.5q + q2 = 0 + 7 Combine like terms: 0 + 7 = 7 0.5q + q2 = 7 The q term is 0.5q. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5q + 0.0625 + q2 = 7 + 0.0625 Reorder the terms: 0.0625 + 0.5q + q2 = 7 + 0.0625 Combine like terms: 7 + 0.0625 = 7.0625 0.0625 + 0.5q + q2 = 7.0625 Factor a perfect square on the left side: (q + 0.25)(q + 0.25) = 7.0625 Calculate the square root of the right side: 2.657536453 Break this problem into two subproblems by setting (q + 0.25) equal to 2.657536453 and -2.657536453.Subproblem 1
q + 0.25 = 2.657536453 Simplifying q + 0.25 = 2.657536453 Reorder the terms: 0.25 + q = 2.657536453 Solving 0.25 + q = 2.657536453 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + q = 2.657536453 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + q = 2.657536453 + -0.25 q = 2.657536453 + -0.25 Combine like terms: 2.657536453 + -0.25 = 2.407536453 q = 2.407536453 Simplifying q = 2.407536453Subproblem 2
q + 0.25 = -2.657536453 Simplifying q + 0.25 = -2.657536453 Reorder the terms: 0.25 + q = -2.657536453 Solving 0.25 + q = -2.657536453 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + q = -2.657536453 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + q = -2.657536453 + -0.25 q = -2.657536453 + -0.25 Combine like terms: -2.657536453 + -0.25 = -2.907536453 q = -2.907536453 Simplifying q = -2.907536453Solution
