Simplifying 0 = x2 + -1.4x + 0.2 Reorder the terms: 0 = 0.2 + -1.4x + x2 Solving 0 = 0.2 + -1.4x + x2 Solving for variable 'x'. Combine like terms: 0 + -0.2 = -0.2 -0.2 + 1.4x + -1x2 = 0.2 + -1.4x + x2 + -0.2 + 1.4x + -1x2 Reorder the terms: -0.2 + 1.4x + -1x2 = 0.2 + -0.2 + -1.4x + 1.4x + x2 + -1x2 Combine like terms: 0.2 + -0.2 = 0.0 -0.2 + 1.4x + -1x2 = 0.0 + -1.4x + 1.4x + x2 + -1x2 -0.2 + 1.4x + -1x2 = -1.4x + 1.4x + x2 + -1x2 Combine like terms: -1.4x + 1.4x = 0.0 -0.2 + 1.4x + -1x2 = 0.0 + x2 + -1x2 -0.2 + 1.4x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -0.2 + 1.4x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 0.2 + -1.4x + x2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -1.4x + -0.2 + x2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -1.4x + x2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -1.4x + x2 = 0 + -0.2 -1.4x + x2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -1.4x + x2 = -0.2 The x term is -1.4x. Take half its coefficient (-0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. -1.4x + 0.49 + x2 = -0.2 + 0.49 Reorder the terms: 0.49 + -1.4x + x2 = -0.2 + 0.49 Combine like terms: -0.2 + 0.49 = 0.29 0.49 + -1.4x + x2 = 0.29 Factor a perfect square on the left side: (x + -0.7)(x + -0.7) = 0.29 Calculate the square root of the right side: 0.538516481 Break this problem into two subproblems by setting (x + -0.7) equal to 0.538516481 and -0.538516481.Subproblem 1
x + -0.7 = 0.538516481 Simplifying x + -0.7 = 0.538516481 Reorder the terms: -0.7 + x = 0.538516481 Solving -0.7 + x = 0.538516481 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.7' to each side of the equation. -0.7 + 0.7 + x = 0.538516481 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + x = 0.538516481 + 0.7 x = 0.538516481 + 0.7 Combine like terms: 0.538516481 + 0.7 = 1.238516481 x = 1.238516481 Simplifying x = 1.238516481Subproblem 2
x + -0.7 = -0.538516481 Simplifying x + -0.7 = -0.538516481 Reorder the terms: -0.7 + x = -0.538516481 Solving -0.7 + x = -0.538516481 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.7' to each side of the equation. -0.7 + 0.7 + x = -0.538516481 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + x = -0.538516481 + 0.7 x = -0.538516481 + 0.7 Combine like terms: -0.538516481 + 0.7 = 0.161483519 x = 0.161483519 Simplifying x = 0.161483519Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.238516481, 0.161483519}
