Subproblem 1

Set the factor '(8 + -3c + 2c2)' equal to zero and attempt to solve: Simplifying 8 + -3c + 2c2 = 0 Solving 8 + -3c + 2c2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4 + -1.5c + c2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + -1.5c + -4 + c2 = 0 + -4 Reorder the terms: 4 + -4 + -1.5c + c2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1.5c + c2 = 0 + -4 -1.5c + c2 = 0 + -4 Combine like terms: 0 + -4 = -4 -1.5c + c2 = -4 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 = -4 + 0.5625 Reorder the terms: 0.5625 + -1.5c + c2 = -4 + 0.5625 Combine like terms: -4 + 0.5625 = -3.4375 0.5625 + -1.5c + c2 = -3.4375 Factor a perfect square on the left side: (c + -0.75)(c + -0.75) = -3.4375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
