Simplifying 0.4x(x + -2) = 0.2 Reorder the terms: 0.4x(-2 + x) = 0.2 (-2 * 0.4x + x * 0.4x) = 0.2 (-0.8x + 0.4x2) = 0.2 Solving -0.8x + 0.4x2 = 0.2 Solving for variable 'x'. Reorder the terms: -0.2 + -0.8x + 0.4x2 = 0.2 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 -0.2 + -0.8x + 0.4x2 = 0.0 Begin completing the square. Divide all terms by 0.4 the coefficient of the squared term: Divide each side by '0.4'. -0.5 + -2x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -2x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -2x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -2x + x2 = 0 + 0.5 -2x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -2x + x2 = 0.5 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 0.5 + 1 Reorder the terms: 1 + -2x + x2 = 0.5 + 1 Combine like terms: 0.5 + 1 = 1.5 1 + -2x + x2 = 1.5 Factor a perfect square on the left side: (x + -1)(x + -1) = 1.5 Calculate the square root of the right side: 1.224744871 Break this problem into two subproblems by setting (x + -1) equal to 1.224744871 and -1.224744871.Subproblem 1
x + -1 = 1.224744871 Simplifying x + -1 = 1.224744871 Reorder the terms: -1 + x = 1.224744871 Solving -1 + x = 1.224744871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.224744871 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.224744871 + 1 x = 1.224744871 + 1 Combine like terms: 1.224744871 + 1 = 2.224744871 x = 2.224744871 Simplifying x = 2.224744871Subproblem 2
x + -1 = -1.224744871 Simplifying x + -1 = -1.224744871 Reorder the terms: -1 + x = -1.224744871 Solving -1 + x = -1.224744871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.224744871 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.224744871 + 1 x = -1.224744871 + 1 Combine like terms: -1.224744871 + 1 = -0.224744871 x = -0.224744871 Simplifying x = -0.224744871Solution
