Simplifying c2 + c + -4 = 0 Reorder the terms: -4 + c + c2 = 0 Solving -4 + c + 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 + c + 4 + c2 = 0 + 4 Reorder the terms: -4 + 4 + c + c2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + c + c2 = 0 + 4 c + c2 = 0 + 4 Combine like terms: 0 + 4 = 4 c + c2 = 4 The c term is c. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. c + 0.25 + c2 = 4 + 0.25 Reorder the terms: 0.25 + c + c2 = 4 + 0.25 Combine like terms: 4 + 0.25 = 4.25 0.25 + c + c2 = 4.25 Factor a perfect square on the left side: (c + 0.5)(c + 0.5) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by setting (c + 0.5) equal to 2.061552813 and -2.061552813.Subproblem 1
c + 0.5 = 2.061552813 Simplifying c + 0.5 = 2.061552813 Reorder the terms: 0.5 + c = 2.061552813 Solving 0.5 + c = 2.061552813 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + c = 2.061552813 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + c = 2.061552813 + -0.5 c = 2.061552813 + -0.5 Combine like terms: 2.061552813 + -0.5 = 1.561552813 c = 1.561552813 Simplifying c = 1.561552813Subproblem 2
c + 0.5 = -2.061552813 Simplifying c + 0.5 = -2.061552813 Reorder the terms: 0.5 + c = -2.061552813 Solving 0.5 + c = -2.061552813 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + c = -2.061552813 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + c = -2.061552813 + -0.5 c = -2.061552813 + -0.5 Combine like terms: -2.061552813 + -0.5 = -2.561552813 c = -2.561552813 Simplifying c = -2.561552813Solution
The solution to the problem is based on the solutions from the subproblems. c = {1.561552813, -2.561552813}
