Simplifying 0.7x2 = 1.4x + 0.7 Reorder the terms: 0.7x2 = 0.7 + 1.4x Solving 0.7x2 = 0.7 + 1.4x Solving for variable 'x'. Reorder the terms: -0.7 + -1.4x + 0.7x2 = 0.7 + 1.4x + -0.7 + -1.4x Reorder the terms: -0.7 + -1.4x + 0.7x2 = 0.7 + -0.7 + 1.4x + -1.4x Combine like terms: 0.7 + -0.7 = 0.0 -0.7 + -1.4x + 0.7x2 = 0.0 + 1.4x + -1.4x -0.7 + -1.4x + 0.7x2 = 1.4x + -1.4x Combine like terms: 1.4x + -1.4x = 0.0 -0.7 + -1.4x + 0.7x2 = 0.0 Begin completing the square. Divide all terms by 0.7 the coefficient of the squared term: Divide each side by '0.7'. -1 + -2x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -2x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -2x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -2x + x2 = 0 + 1 -2x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -2x + x2 = 1 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 = 1 + 1 Reorder the terms: 1 + -2x + x2 = 1 + 1 Combine like terms: 1 + 1 = 2 1 + -2x + x2 = 2 Factor a perfect square on the left side: (x + -1)(x + -1) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + -1) equal to 1.414213562 and -1.414213562.Subproblem 1
x + -1 = 1.414213562 Simplifying x + -1 = 1.414213562 Reorder the terms: -1 + x = 1.414213562 Solving -1 + x = 1.414213562 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 = 1.414213562 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.414213562 + 1 x = 1.414213562 + 1 Combine like terms: 1.414213562 + 1 = 2.414213562 x = 2.414213562 Simplifying x = 2.414213562Subproblem 2
x + -1 = -1.414213562 Simplifying x + -1 = -1.414213562 Reorder the terms: -1 + x = -1.414213562 Solving -1 + x = -1.414213562 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 = -1.414213562 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.414213562 + 1 x = -1.414213562 + 1 Combine like terms: -1.414213562 + 1 = -0.414213562 x = -0.414213562 Simplifying x = -0.414213562Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.414213562, -0.414213562}
