Simplifying 2c2 + 7c = 5 Reorder the terms: 7c + 2c2 = 5 Solving 7c + 2c2 = 5 Solving for variable 'c'. Reorder the terms: -5 + 7c + 2c2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + 7c + 2c2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 3.5c + c2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 3.5c + 2.5 + c2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 3.5c + c2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 3.5c + c2 = 0 + 2.5 3.5c + c2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 3.5c + c2 = 2.5 The c term is 3.5c. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5c + 3.0625 + c2 = 2.5 + 3.0625 Reorder the terms: 3.0625 + 3.5c + c2 = 2.5 + 3.0625 Combine like terms: 2.5 + 3.0625 = 5.5625 3.0625 + 3.5c + c2 = 5.5625 Factor a perfect square on the left side: (c + 1.75)(c + 1.75) = 5.5625 Calculate the square root of the right side: 2.358495283 Break this problem into two subproblems by setting (c + 1.75) equal to 2.358495283 and -2.358495283.Subproblem 1
c + 1.75 = 2.358495283 Simplifying c + 1.75 = 2.358495283 Reorder the terms: 1.75 + c = 2.358495283 Solving 1.75 + c = 2.358495283 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + c = 2.358495283 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + c = 2.358495283 + -1.75 c = 2.358495283 + -1.75 Combine like terms: 2.358495283 + -1.75 = 0.608495283 c = 0.608495283 Simplifying c = 0.608495283Subproblem 2
c + 1.75 = -2.358495283 Simplifying c + 1.75 = -2.358495283 Reorder the terms: 1.75 + c = -2.358495283 Solving 1.75 + c = -2.358495283 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + c = -2.358495283 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + c = -2.358495283 + -1.75 c = -2.358495283 + -1.75 Combine like terms: -2.358495283 + -1.75 = -4.108495283 c = -4.108495283 Simplifying c = -4.108495283Solution
The solution to the problem is based on the solutions from the subproblems. c = {0.608495283, -4.108495283}
