Simplifying x2 + -3x + -1.6 = 0 Reorder the terms: -1.6 + -3x + x2 = 0 Solving -1.6 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + -3x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + -3x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + -3x + x2 = 0 + 1.6 -3x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 -3x + x2 = 1.6 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 1.6 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 1.6 + 2.25 Combine like terms: 1.6 + 2.25 = 3.85 2.25 + -3x + x2 = 3.85 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 3.85 Calculate the square root of the right side: 1.962141687 Break this problem into two subproblems by setting (x + -1.5) equal to 1.962141687 and -1.962141687.Subproblem 1
x + -1.5 = 1.962141687 Simplifying x + -1.5 = 1.962141687 Reorder the terms: -1.5 + x = 1.962141687 Solving -1.5 + x = 1.962141687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 1.962141687 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 1.962141687 + 1.5 x = 1.962141687 + 1.5 Combine like terms: 1.962141687 + 1.5 = 3.462141687 x = 3.462141687 Simplifying x = 3.462141687Subproblem 2
x + -1.5 = -1.962141687 Simplifying x + -1.5 = -1.962141687 Reorder the terms: -1.5 + x = -1.962141687 Solving -1.5 + x = -1.962141687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -1.962141687 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -1.962141687 + 1.5 x = -1.962141687 + 1.5 Combine like terms: -1.962141687 + 1.5 = -0.462141687 x = -0.462141687 Simplifying x = -0.462141687Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.462141687, -0.462141687}
