Simplifying -0.12q2 + 1.8q + -6 = 0 Reorder the terms: -6 + 1.8q + -0.12q2 = 0 Solving -6 + 1.8q + -0.12q2 = 0 Solving for variable 'q'. Begin completing the square. Divide all terms by -0.12 the coefficient of the squared term: Divide each side by '-0.12'. 50 + -15q + q2 = 0 Move the constant term to the right: Add '-50' to each side of the equation. 50 + -15q + -50 + q2 = 0 + -50 Reorder the terms: 50 + -50 + -15q + q2 = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -15q + q2 = 0 + -50 -15q + q2 = 0 + -50 Combine like terms: 0 + -50 = -50 -15q + q2 = -50 The q term is -15q. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15q + 56.25 + q2 = -50 + 56.25 Reorder the terms: 56.25 + -15q + q2 = -50 + 56.25 Combine like terms: -50 + 56.25 = 6.25 56.25 + -15q + q2 = 6.25 Factor a perfect square on the left side: (q + -7.5)(q + -7.5) = 6.25 Calculate the square root of the right side: 2.5 Break this problem into two subproblems by setting (q + -7.5) equal to 2.5 and -2.5.Subproblem 1
q + -7.5 = 2.5 Simplifying q + -7.5 = 2.5 Reorder the terms: -7.5 + q = 2.5 Solving -7.5 + q = 2.5 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + q = 2.5 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + q = 2.5 + 7.5 q = 2.5 + 7.5 Combine like terms: 2.5 + 7.5 = 10 q = 10 Simplifying q = 10Subproblem 2
q + -7.5 = -2.5 Simplifying q + -7.5 = -2.5 Reorder the terms: -7.5 + q = -2.5 Solving -7.5 + q = -2.5 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + q = -2.5 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + q = -2.5 + 7.5 q = -2.5 + 7.5 Combine like terms: -2.5 + 7.5 = 5 q = 5 Simplifying q = 5Solution
The solution to the problem is based on the solutions from the subproblems. q = {10, 5}
