Simplifying c3 + -6c2 + -8c = 0 Reorder the terms: -8c + -6c2 + c3 = 0 Solving -8c + -6c2 + c3 = 0 Solving for variable 'c'. Factor out the Greatest Common Factor (GCF), 'c'. c(-8 + -6c + c2) = 0Subproblem 1
Set the factor 'c' equal to zero and attempt to solve: Simplifying c = 0 Solving c = 0 Move all terms containing c to the left, all other terms to the right. Simplifying c = 0Subproblem 2
Set the factor '(-8 + -6c + c2)' equal to zero and attempt to solve: Simplifying -8 + -6c + c2 = 0 Solving -8 + -6c + c2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + -6c + 8 + c2 = 0 + 8 Reorder the terms: -8 + 8 + -6c + c2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -6c + c2 = 0 + 8 -6c + c2 = 0 + 8 Combine like terms: 0 + 8 = 8 -6c + c2 = 8 The c term is -6c. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6c + 9 + c2 = 8 + 9 Reorder the terms: 9 + -6c + c2 = 8 + 9 Combine like terms: 8 + 9 = 17 9 + -6c + c2 = 17 Factor a perfect square on the left side: (c + -3)(c + -3) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (c + -3) equal to 4.123105626 and -4.123105626.Subproblem 1
c + -3 = 4.123105626 Simplifying c + -3 = 4.123105626 Reorder the terms: -3 + c = 4.123105626 Solving -3 + c = 4.123105626 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + c = 4.123105626 + 3 Combine like terms: -3 + 3 = 0 0 + c = 4.123105626 + 3 c = 4.123105626 + 3 Combine like terms: 4.123105626 + 3 = 7.123105626 c = 7.123105626 Simplifying c = 7.123105626Subproblem 2
c + -3 = -4.123105626 Simplifying c + -3 = -4.123105626 Reorder the terms: -3 + c = -4.123105626 Solving -3 + c = -4.123105626 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + c = -4.123105626 + 3 Combine like terms: -3 + 3 = 0 0 + c = -4.123105626 + 3 c = -4.123105626 + 3 Combine like terms: -4.123105626 + 3 = -1.123105626 c = -1.123105626 Simplifying c = -1.123105626Solution
