Simplifying 2c2 + 3c + -10 = 0 Reorder the terms: -10 + 3c + 2c2 = 0 Solving -10 + 3c + 2c2 = 0 Solving for variable 'c'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -5 + 1.5c + c2 = 0 Move the constant term to the right: Add '5' to each side of the equation. -5 + 1.5c + 5 + c2 = 0 + 5 Reorder the terms: -5 + 5 + 1.5c + c2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 1.5c + c2 = 0 + 5 1.5c + c2 = 0 + 5 Combine like terms: 0 + 5 = 5 1.5c + c2 = 5 The c term is 1.5c. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5c + 0.5625 + c2 = 5 + 0.5625 Reorder the terms: 0.5625 + 1.5c + c2 = 5 + 0.5625 Combine like terms: 5 + 0.5625 = 5.5625 0.5625 + 1.5c + c2 = 5.5625 Factor a perfect square on the left side: (c + 0.75)(c + 0.75) = 5.5625 Calculate the square root of the right side: 2.358495283 Break this problem into two subproblems by setting (c + 0.75) equal to 2.358495283 and -2.358495283.Subproblem 1
c + 0.75 = 2.358495283 Simplifying c + 0.75 = 2.358495283 Reorder the terms: 0.75 + c = 2.358495283 Solving 0.75 + c = 2.358495283 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + c = 2.358495283 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + c = 2.358495283 + -0.75 c = 2.358495283 + -0.75 Combine like terms: 2.358495283 + -0.75 = 1.608495283 c = 1.608495283 Simplifying c = 1.608495283Subproblem 2
c + 0.75 = -2.358495283 Simplifying c + 0.75 = -2.358495283 Reorder the terms: 0.75 + c = -2.358495283 Solving 0.75 + c = -2.358495283 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + c = -2.358495283 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + c = -2.358495283 + -0.75 c = -2.358495283 + -0.75 Combine like terms: -2.358495283 + -0.75 = -3.108495283 c = -3.108495283 Simplifying c = -3.108495283Solution
