Simplifying x2 + 2.25x + -0.6 = 0 Reorder the terms: -0.6 + 2.25x + x2 = 0 Solving -0.6 + 2.25x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + 2.25x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + 2.25x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + 2.25x + x2 = 0 + 0.6 2.25x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 2.25x + x2 = 0.6 The x term is 2.25x. Take half its coefficient (1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. 2.25x + 1.265625 + x2 = 0.6 + 1.265625 Reorder the terms: 1.265625 + 2.25x + x2 = 0.6 + 1.265625 Combine like terms: 0.6 + 1.265625 = 1.865625 1.265625 + 2.25x + x2 = 1.865625 Factor a perfect square on the left side: (x + 1.125)(x + 1.125) = 1.865625 Calculate the square root of the right side: 1.365878838 Break this problem into two subproblems by setting (x + 1.125) equal to 1.365878838 and -1.365878838.Subproblem 1
x + 1.125 = 1.365878838 Simplifying x + 1.125 = 1.365878838 Reorder the terms: 1.125 + x = 1.365878838 Solving 1.125 + x = 1.365878838 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = 1.365878838 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = 1.365878838 + -1.125 x = 1.365878838 + -1.125 Combine like terms: 1.365878838 + -1.125 = 0.240878838 x = 0.240878838 Simplifying x = 0.240878838Subproblem 2
x + 1.125 = -1.365878838 Simplifying x + 1.125 = -1.365878838 Reorder the terms: 1.125 + x = -1.365878838 Solving 1.125 + x = -1.365878838 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = -1.365878838 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = -1.365878838 + -1.125 x = -1.365878838 + -1.125 Combine like terms: -1.365878838 + -1.125 = -2.490878838 x = -2.490878838 Simplifying x = -2.490878838Solution
