Simplifying x2 + 1.8x + -0.1152 = 0 Reorder the terms: -0.1152 + 1.8x + x2 = 0 Solving -0.1152 + 1.8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.1152' to each side of the equation. -0.1152 + 1.8x + 0.1152 + x2 = 0 + 0.1152 Reorder the terms: -0.1152 + 0.1152 + 1.8x + x2 = 0 + 0.1152 Combine like terms: -0.1152 + 0.1152 = 0.0000 0.0000 + 1.8x + x2 = 0 + 0.1152 1.8x + x2 = 0 + 0.1152 Combine like terms: 0 + 0.1152 = 0.1152 1.8x + x2 = 0.1152 The x term is 1.8x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8x + 0.81 + x2 = 0.1152 + 0.81 Reorder the terms: 0.81 + 1.8x + x2 = 0.1152 + 0.81 Combine like terms: 0.1152 + 0.81 = 0.9252 0.81 + 1.8x + x2 = 0.9252 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = 0.9252 Calculate the square root of the right side: 0.961873173 Break this problem into two subproblems by setting (x + 0.9) equal to 0.961873173 and -0.961873173.Subproblem 1
x + 0.9 = 0.961873173 Simplifying x + 0.9 = 0.961873173 Reorder the terms: 0.9 + x = 0.961873173 Solving 0.9 + x = 0.961873173 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = 0.961873173 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = 0.961873173 + -0.9 x = 0.961873173 + -0.9 Combine like terms: 0.961873173 + -0.9 = 0.061873173 x = 0.061873173 Simplifying x = 0.061873173Subproblem 2
x + 0.9 = -0.961873173 Simplifying x + 0.9 = -0.961873173 Reorder the terms: 0.9 + x = -0.961873173 Solving 0.9 + x = -0.961873173 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = -0.961873173 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = -0.961873173 + -0.9 x = -0.961873173 + -0.9 Combine like terms: -0.961873173 + -0.9 = -1.861873173 x = -1.861873173 Simplifying x = -1.861873173Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.061873173, -1.861873173}
