Simplifying x2 + -51 = -2x Reorder the terms: -51 + x2 = -2x Solving -51 + x2 = -2x Solving for variable 'x'. Reorder the terms: -51 + 2x + x2 = -2x + 2x Combine like terms: -2x + 2x = 0 -51 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '51' to each side of the equation. -51 + 2x + 51 + x2 = 0 + 51 Reorder the terms: -51 + 51 + 2x + x2 = 0 + 51 Combine like terms: -51 + 51 = 0 0 + 2x + x2 = 0 + 51 2x + x2 = 0 + 51 Combine like terms: 0 + 51 = 51 2x + x2 = 51 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 = 51 + 1 Reorder the terms: 1 + 2x + x2 = 51 + 1 Combine like terms: 51 + 1 = 52 1 + 2x + x2 = 52 Factor a perfect square on the left side: (x + 1)(x + 1) = 52 Calculate the square root of the right side: 7.211102551 Break this problem into two subproblems by setting (x + 1) equal to 7.211102551 and -7.211102551.Subproblem 1
x + 1 = 7.211102551 Simplifying x + 1 = 7.211102551 Reorder the terms: 1 + x = 7.211102551 Solving 1 + x = 7.211102551 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 = 7.211102551 + -1 Combine like terms: 1 + -1 = 0 0 + x = 7.211102551 + -1 x = 7.211102551 + -1 Combine like terms: 7.211102551 + -1 = 6.211102551 x = 6.211102551 Simplifying x = 6.211102551Subproblem 2
x + 1 = -7.211102551 Simplifying x + 1 = -7.211102551 Reorder the terms: 1 + x = -7.211102551 Solving 1 + x = -7.211102551 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 = -7.211102551 + -1 Combine like terms: 1 + -1 = 0 0 + x = -7.211102551 + -1 x = -7.211102551 + -1 Combine like terms: -7.211102551 + -1 = -8.211102551 x = -8.211102551 Simplifying x = -8.211102551Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.211102551, -8.211102551}
