Simplifying C2 + -6C + 4 = 0 Reorder the terms: 4 + -6C + C2 = 0 Solving 4 + -6C + C2 = 0 Solving for variable 'C'. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -6C + -4 + C2 = 0 + -4 Reorder the terms: 4 + -4 + -6C + C2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -6C + C2 = 0 + -4 -6C + C2 = 0 + -4 Combine like terms: 0 + -4 = -4 -6C + C2 = -4 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 = -4 + 9 Reorder the terms: 9 + -6C + C2 = -4 + 9 Combine like terms: -4 + 9 = 5 9 + -6C + C2 = 5 Factor a perfect square on the left side: (C + -3)(C + -3) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (C + -3) equal to 2.236067978 and -2.236067978.Subproblem 1
C + -3 = 2.236067978 Simplifying C + -3 = 2.236067978 Reorder the terms: -3 + C = 2.236067978 Solving -3 + C = 2.236067978 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 = 2.236067978 + 3 Combine like terms: -3 + 3 = 0 0 + C = 2.236067978 + 3 C = 2.236067978 + 3 Combine like terms: 2.236067978 + 3 = 5.236067978 C = 5.236067978 Simplifying C = 5.236067978Subproblem 2
C + -3 = -2.236067978 Simplifying C + -3 = -2.236067978 Reorder the terms: -3 + C = -2.236067978 Solving -3 + C = -2.236067978 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 = -2.236067978 + 3 Combine like terms: -3 + 3 = 0 0 + C = -2.236067978 + 3 C = -2.236067978 + 3 Combine like terms: -2.236067978 + 3 = 0.763932022 C = 0.763932022 Simplifying C = 0.763932022Solution
