Simplifying 273A + 273A2 = 573.3 Solving 273A + 273A2 = 573.3 Solving for variable 'A'. Reorder the terms: -573.3 + 273A + 273A2 = 573.3 + -573.3 Combine like terms: 573.3 + -573.3 = 0.0 -573.3 + 273A + 273A2 = 0.0 Begin completing the square. Divide all terms by 273 the coefficient of the squared term: Divide each side by '273'. -2.1 + A + A2 = 0.0 Move the constant term to the right: Add '2.1' to each side of the equation. -2.1 + A + 2.1 + A2 = 0.0 + 2.1 Reorder the terms: -2.1 + 2.1 + A + A2 = 0.0 + 2.1 Combine like terms: -2.1 + 2.1 = 0.0 0.0 + A + A2 = 0.0 + 2.1 A + A2 = 0.0 + 2.1 Combine like terms: 0.0 + 2.1 = 2.1 A + A2 = 2.1 The A term is A. 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. + 0.25 + A2 = 2.1 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + A2 = 2.1 + 0.25 Combine like terms: 2.1 + 0.25 = 2.35 1.25 + A2 = 2.35 Factor a perfect square on the left side: (A + 0.5)(A + 0.5) = 2.35 Calculate the square root of the right side: 1.532970972 Break this problem into two subproblems by setting (A + 0.5) equal to 1.532970972 and -1.532970972.Subproblem 1
A + 0.5 = 1.532970972 Simplifying A + 0.5 = 1.532970972 Reorder the terms: 0.5 + A = 1.532970972 Solving 0.5 + A = 1.532970972 Solving for variable 'A'. Move all terms containing A to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + A = 1.532970972 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + A = 1.532970972 + -0.5 A = 1.532970972 + -0.5 Combine like terms: 1.532970972 + -0.5 = 1.032970972 A = 1.032970972 Simplifying A = 1.032970972Subproblem 2
A + 0.5 = -1.532970972 Simplifying A + 0.5 = -1.532970972 Reorder the terms: 0.5 + A = -1.532970972 Solving 0.5 + A = -1.532970972 Solving for variable 'A'. Move all terms containing A to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + A = -1.532970972 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + A = -1.532970972 + -0.5 A = -1.532970972 + -0.5 Combine like terms: -1.532970972 + -0.5 = -2.032970972 A = -2.032970972 Simplifying A = -2.032970972Solution
The solution to the problem is based on the solutions from the subproblems. A = {1.032970972, -2.032970972}
