Simplifying -5x2 + -2x + 17 = 0 Reorder the terms: 17 + -2x + -5x2 = 0 Solving 17 + -2x + -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'. -3.4 + 0.4x + x2 = 0 Move the constant term to the right: Add '3.4' to each side of the equation. -3.4 + 0.4x + 3.4 + x2 = 0 + 3.4 Reorder the terms: -3.4 + 3.4 + 0.4x + x2 = 0 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + 0.4x + x2 = 0 + 3.4 0.4x + x2 = 0 + 3.4 Combine like terms: 0 + 3.4 = 3.4 0.4x + x2 = 3.4 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = 3.4 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = 3.4 + 0.04 Combine like terms: 3.4 + 0.04 = 3.44 0.04 + 0.4x + x2 = 3.44 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = 3.44 Calculate the square root of the right side: 1.854723699 Break this problem into two subproblems by setting (x + 0.2) equal to 1.854723699 and -1.854723699.Subproblem 1
x + 0.2 = 1.854723699 Simplifying x + 0.2 = 1.854723699 Reorder the terms: 0.2 + x = 1.854723699 Solving 0.2 + x = 1.854723699 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = 1.854723699 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = 1.854723699 + -0.2 x = 1.854723699 + -0.2 Combine like terms: 1.854723699 + -0.2 = 1.654723699 x = 1.654723699 Simplifying x = 1.654723699Subproblem 2
x + 0.2 = -1.854723699 Simplifying x + 0.2 = -1.854723699 Reorder the terms: 0.2 + x = -1.854723699 Solving 0.2 + x = -1.854723699 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = -1.854723699 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = -1.854723699 + -0.2 x = -1.854723699 + -0.2 Combine like terms: -1.854723699 + -0.2 = -2.054723699 x = -2.054723699 Simplifying x = -2.054723699Solution
