Simplifying x2 + -2x + -43 = 0 Reorder the terms: -43 + -2x + x2 = 0 Solving -43 + -2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '43' to each side of the equation. -43 + -2x + 43 + x2 = 0 + 43 Reorder the terms: -43 + 43 + -2x + x2 = 0 + 43 Combine like terms: -43 + 43 = 0 0 + -2x + x2 = 0 + 43 -2x + x2 = 0 + 43 Combine like terms: 0 + 43 = 43 -2x + x2 = 43 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 = 43 + 1 Reorder the terms: 1 + -2x + x2 = 43 + 1 Combine like terms: 43 + 1 = 44 1 + -2x + x2 = 44 Factor a perfect square on the left side: (x + -1)(x + -1) = 44 Calculate the square root of the right side: 6.633249581 Break this problem into two subproblems by setting (x + -1) equal to 6.633249581 and -6.633249581.Subproblem 1
x + -1 = 6.633249581 Simplifying x + -1 = 6.633249581 Reorder the terms: -1 + x = 6.633249581 Solving -1 + x = 6.633249581 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 = 6.633249581 + 1 Combine like terms: -1 + 1 = 0 0 + x = 6.633249581 + 1 x = 6.633249581 + 1 Combine like terms: 6.633249581 + 1 = 7.633249581 x = 7.633249581 Simplifying x = 7.633249581Subproblem 2
x + -1 = -6.633249581 Simplifying x + -1 = -6.633249581 Reorder the terms: -1 + x = -6.633249581 Solving -1 + x = -6.633249581 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 = -6.633249581 + 1 Combine like terms: -1 + 1 = 0 0 + x = -6.633249581 + 1 x = -6.633249581 + 1 Combine like terms: -6.633249581 + 1 = -5.633249581 x = -5.633249581 Simplifying x = -5.633249581Solution
