Simplifying 0.6x2 + -0.24x = 0.16 Reorder the terms: -0.24x + 0.6x2 = 0.16 Solving -0.24x + 0.6x2 = 0.16 Solving for variable 'x'. Reorder the terms: -0.16 + -0.24x + 0.6x2 = 0.16 + -0.16 Combine like terms: 0.16 + -0.16 = 0.00 -0.16 + -0.24x + 0.6x2 = 0.00 Begin completing the square. Divide all terms by 0.6 the coefficient of the squared term: Divide each side by '0.6'. -0.2666666667 + -0.4x + x2 = 0.0 Move the constant term to the right: Add '0.2666666667' to each side of the equation. -0.2666666667 + -0.4x + 0.2666666667 + x2 = 0.0 + 0.2666666667 Reorder the terms: -0.2666666667 + 0.2666666667 + -0.4x + x2 = 0.0 + 0.2666666667 Combine like terms: -0.2666666667 + 0.2666666667 = 0.0000000000 0.0000000000 + -0.4x + x2 = 0.0 + 0.2666666667 -0.4x + x2 = 0.0 + 0.2666666667 Combine like terms: 0.0 + 0.2666666667 = 0.2666666667 -0.4x + x2 = 0.2666666667 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 = 0.2666666667 + 0.04 Reorder the terms: 0.04 + -0.4x + x2 = 0.2666666667 + 0.04 Combine like terms: 0.2666666667 + 0.04 = 0.3066666667 0.04 + -0.4x + x2 = 0.3066666667 Factor a perfect square on the left side: (x + -0.2)(x + -0.2) = 0.3066666667 Calculate the square root of the right side: 0.553774924 Break this problem into two subproblems by setting (x + -0.2) equal to 0.553774924 and -0.553774924.Subproblem 1
x + -0.2 = 0.553774924 Simplifying x + -0.2 = 0.553774924 Reorder the terms: -0.2 + x = 0.553774924 Solving -0.2 + x = 0.553774924 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 = 0.553774924 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = 0.553774924 + 0.2 x = 0.553774924 + 0.2 Combine like terms: 0.553774924 + 0.2 = 0.753774924 x = 0.753774924 Simplifying x = 0.753774924Subproblem 2
x + -0.2 = -0.553774924 Simplifying x + -0.2 = -0.553774924 Reorder the terms: -0.2 + x = -0.553774924 Solving -0.2 + x = -0.553774924 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 = -0.553774924 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = -0.553774924 + 0.2 x = -0.553774924 + 0.2 Combine like terms: -0.553774924 + 0.2 = -0.353774924 x = -0.353774924 Simplifying x = -0.353774924Solution
