Simplifying (0.2x2) + -0.8x + -0.2 = 0 Reorder the terms: -0.2 + -0.8x + (0.2x2) = 0 Solving -0.2 + -0.8x + (0.2x2) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. -1 + -4x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -4x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -4x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -4x + x2 = 0 + 1 -4x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -4x + x2 = 1 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 1 + 4 Reorder the terms: 4 + -4x + x2 = 1 + 4 Combine like terms: 1 + 4 = 5 4 + -4x + x2 = 5 Factor a perfect square on the left side: ((x) + -2)((x) + -2) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting ((x) + -2) equal to 2.236067978 and -2.236067978.Subproblem 1
(x) + -2 = 2.236067978 Simplifying (x) + -2 = 2.236067978 x + -2 = 2.236067978 Reorder the terms: -2 + x = 2.236067978 Solving -2 + x = 2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 2.236067978 + 2 Combine like terms: -2 + 2 = 0 0 + x = 2.236067978 + 2 x = 2.236067978 + 2 Combine like terms: 2.236067978 + 2 = 4.236067978 x = 4.236067978 Simplifying x = 4.236067978Subproblem 2
(x) + -2 = -2.236067978 Simplifying (x) + -2 = -2.236067978 x + -2 = -2.236067978 Reorder the terms: -2 + x = -2.236067978 Solving -2 + x = -2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -2.236067978 + 2 Combine like terms: -2 + 2 = 0 0 + x = -2.236067978 + 2 x = -2.236067978 + 2 Combine like terms: -2.236067978 + 2 = -0.236067978 x = -0.236067978 Simplifying x = -0.236067978Solution
