Simplifying x2 + 28x + 2 = 0 Reorder the terms: 2 + 28x + x2 = 0 Solving 2 + 28x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 28x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + 28x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 28x + x2 = 0 + -2 28x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 28x + x2 = -2 The x term is 28x. Take half its coefficient (14). Square it (196) and add it to both sides. Add '196' to each side of the equation. 28x + 196 + x2 = -2 + 196 Reorder the terms: 196 + 28x + x2 = -2 + 196 Combine like terms: -2 + 196 = 194 196 + 28x + x2 = 194 Factor a perfect square on the left side: (x + 14)(x + 14) = 194 Calculate the square root of the right side: 13.928388277 Break this problem into two subproblems by setting (x + 14) equal to 13.928388277 and -13.928388277.Subproblem 1
x + 14 = 13.928388277 Simplifying x + 14 = 13.928388277 Reorder the terms: 14 + x = 13.928388277 Solving 14 + x = 13.928388277 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + x = 13.928388277 + -14 Combine like terms: 14 + -14 = 0 0 + x = 13.928388277 + -14 x = 13.928388277 + -14 Combine like terms: 13.928388277 + -14 = -0.071611723 x = -0.071611723 Simplifying x = -0.071611723Subproblem 2
x + 14 = -13.928388277 Simplifying x + 14 = -13.928388277 Reorder the terms: 14 + x = -13.928388277 Solving 14 + x = -13.928388277 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + x = -13.928388277 + -14 Combine like terms: 14 + -14 = 0 0 + x = -13.928388277 + -14 x = -13.928388277 + -14 Combine like terms: -13.928388277 + -14 = -27.928388277 x = -27.928388277 Simplifying x = -27.928388277Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.071611723, -27.928388277}
