Simplifying 5x2 + 62x + 40 = 0 Reorder the terms: 40 + 62x + 5x2 = 0 Solving 40 + 62x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 8 + 12.4x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + 12.4x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + 12.4x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 12.4x + x2 = 0 + -8 12.4x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 12.4x + x2 = -8 The x term is 12.4x. Take half its coefficient (6.2). Square it (38.44) and add it to both sides. Add '38.44' to each side of the equation. 12.4x + 38.44 + x2 = -8 + 38.44 Reorder the terms: 38.44 + 12.4x + x2 = -8 + 38.44 Combine like terms: -8 + 38.44 = 30.44 38.44 + 12.4x + x2 = 30.44 Factor a perfect square on the left side: (x + 6.2)(x + 6.2) = 30.44 Calculate the square root of the right side: 5.51724569 Break this problem into two subproblems by setting (x + 6.2) equal to 5.51724569 and -5.51724569.Subproblem 1
x + 6.2 = 5.51724569 Simplifying x + 6.2 = 5.51724569 Reorder the terms: 6.2 + x = 5.51724569 Solving 6.2 + x = 5.51724569 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.2' to each side of the equation. 6.2 + -6.2 + x = 5.51724569 + -6.2 Combine like terms: 6.2 + -6.2 = 0.0 0.0 + x = 5.51724569 + -6.2 x = 5.51724569 + -6.2 Combine like terms: 5.51724569 + -6.2 = -0.68275431 x = -0.68275431 Simplifying x = -0.68275431Subproblem 2
x + 6.2 = -5.51724569 Simplifying x + 6.2 = -5.51724569 Reorder the terms: 6.2 + x = -5.51724569 Solving 6.2 + x = -5.51724569 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.2' to each side of the equation. 6.2 + -6.2 + x = -5.51724569 + -6.2 Combine like terms: 6.2 + -6.2 = 0.0 0.0 + x = -5.51724569 + -6.2 x = -5.51724569 + -6.2 Combine like terms: -5.51724569 + -6.2 = -11.71724569 x = -11.71724569 Simplifying x = -11.71724569Solution
