Simplifying -2c2 + -3c + 3 = 0 Reorder the terms: 3 + -3c + -2c2 = 0 Solving 3 + -3c + -2c2 = 0 Solving for variable 'c'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -1.5 + 1.5c + c2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 1.5c + 1.5 + c2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 1.5c + c2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 1.5c + c2 = 0 + 1.5 1.5c + c2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 1.5c + c2 = 1.5 The c term is 1.5c. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5c + 0.5625 + c2 = 1.5 + 0.5625 Reorder the terms: 0.5625 + 1.5c + c2 = 1.5 + 0.5625 Combine like terms: 1.5 + 0.5625 = 2.0625 0.5625 + 1.5c + c2 = 2.0625 Factor a perfect square on the left side: (c + 0.75)(c + 0.75) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (c + 0.75) equal to 1.436140662 and -1.436140662.Subproblem 1
c + 0.75 = 1.436140662 Simplifying c + 0.75 = 1.436140662 Reorder the terms: 0.75 + c = 1.436140662 Solving 0.75 + c = 1.436140662 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + c = 1.436140662 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + c = 1.436140662 + -0.75 c = 1.436140662 + -0.75 Combine like terms: 1.436140662 + -0.75 = 0.686140662 c = 0.686140662 Simplifying c = 0.686140662Subproblem 2
c + 0.75 = -1.436140662 Simplifying c + 0.75 = -1.436140662 Reorder the terms: 0.75 + c = -1.436140662 Solving 0.75 + c = -1.436140662 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + c = -1.436140662 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + c = -1.436140662 + -0.75 c = -1.436140662 + -0.75 Combine like terms: -1.436140662 + -0.75 = -2.186140662 c = -2.186140662 Simplifying c = -2.186140662Solution
The solution to the problem is based on the solutions from the subproblems. c = {0.686140662, -2.186140662}
