Simplifying x + 2(x2 + -7) = 0 Reorder the terms: x + 2(-7 + x2) = 0 x + (-7 * 2 + x2 * 2) = 0 x + (-14 + 2x2) = 0 Reorder the terms: -14 + x + 2x2 = 0 Solving -14 + x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -7 + 0.5x + x2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 0.5x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + 0.5x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 0.5x + x2 = 0 + 7 0.5x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 0.5x + x2 = 7 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5x + 0.25 + x2 = 7 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = 7 + 0.25 Combine like terms: 7 + 0.25 = 7.25 0.25 + 0.5x + x2 = 7.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 7.25 Calculate the square root of the right side: 2.692582404 Break this problem into two subproblems by setting (x + 0.5) equal to 2.692582404 and -2.692582404.Subproblem 1
x + 0.5 = 2.692582404 Simplifying x + 0.5 = 2.692582404 Reorder the terms: 0.5 + x = 2.692582404 Solving 0.5 + x = 2.692582404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 2.692582404 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 2.692582404 + -0.5 x = 2.692582404 + -0.5 Combine like terms: 2.692582404 + -0.5 = 2.192582404 x = 2.192582404 Simplifying x = 2.192582404Subproblem 2
x + 0.5 = -2.692582404 Simplifying x + 0.5 = -2.692582404 Reorder the terms: 0.5 + x = -2.692582404 Solving 0.5 + x = -2.692582404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -2.692582404 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -2.692582404 + -0.5 x = -2.692582404 + -0.5 Combine like terms: -2.692582404 + -0.5 = -3.192582404 x = -3.192582404 Simplifying x = -3.192582404Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.192582404, -3.192582404}
