Simplifying x2 + 6.4x + 10.24 = 0 Reorder the terms: 10.24 + 6.4x + x2 = 0 Solving 10.24 + 6.4x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-10.24' to each side of the equation. 10.24 + 6.4x + -10.24 + x2 = 0 + -10.24 Reorder the terms: 10.24 + -10.24 + 6.4x + x2 = 0 + -10.24 Combine like terms: 10.24 + -10.24 = 0.00 0.00 + 6.4x + x2 = 0 + -10.24 6.4x + x2 = 0 + -10.24 Combine like terms: 0 + -10.24 = -10.24 6.4x + x2 = -10.24 The x term is 6.4x. Take half its coefficient (3.2). Square it (10.24) and add it to both sides. Add '10.24' to each side of the equation. 6.4x + 10.24 + x2 = -10.24 + 10.24 Reorder the terms: 10.24 + 6.4x + x2 = -10.24 + 10.24 Combine like terms: -10.24 + 10.24 = 0.00 10.24 + 6.4x + x2 = 0.00 Factor a perfect square on the left side: (x + 3.2)(x + 3.2) = 0.00 Calculate the square root of the right side: 0.00 Break this problem into two subproblems by setting (x + 3.2) equal to 0.00 and 0.00.Subproblem 1
x + 3.2 = 0.00 Simplifying x + 3.2 = 0.00 Reorder the terms: 3.2 + x = 0.00 Solving 3.2 + x = 0.00 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + x = 0.00 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + x = 0.00 + -3.2 x = 0.00 + -3.2 Combine like terms: 0.00 + -3.2 = -3.2 x = -3.2 Simplifying x = -3.2Subproblem 2
x + 3.2 = 0.00 Simplifying x + 3.2 = 0.00 Reorder the terms: 3.2 + x = 0.00 Solving 3.2 + x = 0.00 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + x = 0.00 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + x = 0.00 + -3.2 x = 0.00 + -3.2 Combine like terms: 0.00 + -3.2 = -3.2 x = -3.2 Simplifying x = -3.2Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.2, -3.2}
