Simplifying 20x2 + 19x + -10 = 0 Reorder the terms: -10 + 19x + 20x2 = 0 Solving -10 + 19x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -0.5 + 0.95x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 0.95x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 0.95x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 0.95x + x2 = 0 + 0.5 0.95x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 0.95x + x2 = 0.5 The x term is 0.95x. Take half its coefficient (0.475). Square it (0.225625) and add it to both sides. Add '0.225625' to each side of the equation. 0.95x + 0.225625 + x2 = 0.5 + 0.225625 Reorder the terms: 0.225625 + 0.95x + x2 = 0.5 + 0.225625 Combine like terms: 0.5 + 0.225625 = 0.725625 0.225625 + 0.95x + x2 = 0.725625 Factor a perfect square on the left side: (x + 0.475)(x + 0.475) = 0.725625 Calculate the square root of the right side: 0.851836252 Break this problem into two subproblems by setting (x + 0.475) equal to 0.851836252 and -0.851836252.Subproblem 1
x + 0.475 = 0.851836252 Simplifying x + 0.475 = 0.851836252 Reorder the terms: 0.475 + x = 0.851836252 Solving 0.475 + x = 0.851836252 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.475' to each side of the equation. 0.475 + -0.475 + x = 0.851836252 + -0.475 Combine like terms: 0.475 + -0.475 = 0.000 0.000 + x = 0.851836252 + -0.475 x = 0.851836252 + -0.475 Combine like terms: 0.851836252 + -0.475 = 0.376836252 x = 0.376836252 Simplifying x = 0.376836252Subproblem 2
x + 0.475 = -0.851836252 Simplifying x + 0.475 = -0.851836252 Reorder the terms: 0.475 + x = -0.851836252 Solving 0.475 + x = -0.851836252 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.475' to each side of the equation. 0.475 + -0.475 + x = -0.851836252 + -0.475 Combine like terms: 0.475 + -0.475 = 0.000 0.000 + x = -0.851836252 + -0.475 x = -0.851836252 + -0.475 Combine like terms: -0.851836252 + -0.475 = -1.326836252 x = -1.326836252 Simplifying x = -1.326836252Solution
