Simplifying c2 + 3c + -1 = 0 Reorder the terms: -1 + 3c + c2 = 0 Solving -1 + 3c + c2 = 0 Solving for variable 'c'. Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + 3c + 1 + c2 = 0 + 1 Reorder the terms: -1 + 1 + 3c + c2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 3c + c2 = 0 + 1 3c + c2 = 0 + 1 Combine like terms: 0 + 1 = 1 3c + c2 = 1 The c term is 3c. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3c + 2.25 + c2 = 1 + 2.25 Reorder the terms: 2.25 + 3c + c2 = 1 + 2.25 Combine like terms: 1 + 2.25 = 3.25 2.25 + 3c + c2 = 3.25 Factor a perfect square on the left side: (c + 1.5)(c + 1.5) = 3.25 Calculate the square root of the right side: 1.802775638 Break this problem into two subproblems by setting (c + 1.5) equal to 1.802775638 and -1.802775638.Subproblem 1
c + 1.5 = 1.802775638 Simplifying c + 1.5 = 1.802775638 Reorder the terms: 1.5 + c = 1.802775638 Solving 1.5 + c = 1.802775638 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + c = 1.802775638 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + c = 1.802775638 + -1.5 c = 1.802775638 + -1.5 Combine like terms: 1.802775638 + -1.5 = 0.302775638 c = 0.302775638 Simplifying c = 0.302775638Subproblem 2
c + 1.5 = -1.802775638 Simplifying c + 1.5 = -1.802775638 Reorder the terms: 1.5 + c = -1.802775638 Solving 1.5 + c = -1.802775638 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + c = -1.802775638 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + c = -1.802775638 + -1.5 c = -1.802775638 + -1.5 Combine like terms: -1.802775638 + -1.5 = -3.302775638 c = -3.302775638 Simplifying c = -3.302775638Solution
The solution to the problem is based on the solutions from the subproblems. c = {0.302775638, -3.302775638}
