Subproblem 1

Set the factor '(4 + -3c + c2)' equal to zero and attempt to solve: Simplifying 4 + -3c + c2 = 0 Solving 4 + -3c + c2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -3c + -4 + c2 = 0 + -4 Reorder the terms: 4 + -4 + -3c + c2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -3c + c2 = 0 + -4 -3c + c2 = 0 + -4 Combine like terms: 0 + -4 = -4 -3c + c2 = -4 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 = -4 + 2.25 Reorder the terms: 2.25 + -3c + c2 = -4 + 2.25 Combine like terms: -4 + 2.25 = -1.75 2.25 + -3c + c2 = -1.75 Factor a perfect square on the left side: (c + -1.5)(c + -1.5) = -1.75 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.
