Simplifying 2c2 + -10c = 25 Reorder the terms: -10c + 2c2 = 25 Solving -10c + 2c2 = 25 Solving for variable 'c'. Reorder the terms: -25 + -10c + 2c2 = 25 + -25 Combine like terms: 25 + -25 = 0 -25 + -10c + 2c2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -12.5 + -5c + c2 = 0 Move the constant term to the right: Add '12.5' to each side of the equation. -12.5 + -5c + 12.5 + c2 = 0 + 12.5 Reorder the terms: -12.5 + 12.5 + -5c + c2 = 0 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + -5c + c2 = 0 + 12.5 -5c + c2 = 0 + 12.5 Combine like terms: 0 + 12.5 = 12.5 -5c + c2 = 12.5 The c term is -5c. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5c + 6.25 + c2 = 12.5 + 6.25 Reorder the terms: 6.25 + -5c + c2 = 12.5 + 6.25 Combine like terms: 12.5 + 6.25 = 18.75 6.25 + -5c + c2 = 18.75 Factor a perfect square on the left side: (c + -2.5)(c + -2.5) = 18.75 Calculate the square root of the right side: 4.330127019 Break this problem into two subproblems by setting (c + -2.5) equal to 4.330127019 and -4.330127019.Subproblem 1
c + -2.5 = 4.330127019 Simplifying c + -2.5 = 4.330127019 Reorder the terms: -2.5 + c = 4.330127019 Solving -2.5 + c = 4.330127019 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + c = 4.330127019 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + c = 4.330127019 + 2.5 c = 4.330127019 + 2.5 Combine like terms: 4.330127019 + 2.5 = 6.830127019 c = 6.830127019 Simplifying c = 6.830127019Subproblem 2
c + -2.5 = -4.330127019 Simplifying c + -2.5 = -4.330127019 Reorder the terms: -2.5 + c = -4.330127019 Solving -2.5 + c = -4.330127019 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + c = -4.330127019 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + c = -4.330127019 + 2.5 c = -4.330127019 + 2.5 Combine like terms: -4.330127019 + 2.5 = -1.830127019 c = -1.830127019 Simplifying c = -1.830127019Solution
