Simplifying x2 = -4x + 1 Reorder the terms: x2 = 1 + -4x Solving x2 = 1 + -4x Solving for variable 'x'. Reorder the terms: -1 + 4x + x2 = 1 + -4x + -1 + 4x Reorder the terms: -1 + 4x + x2 = 1 + -1 + -4x + 4x Combine like terms: 1 + -1 = 0 -1 + 4x + x2 = 0 + -4x + 4x -1 + 4x + x2 = -4x + 4x Combine like terms: -4x + 4x = 0 -1 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + 4x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 4x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 4x + x2 = 0 + 1 4x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 4x + x2 = 1 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 1 + 4 Reorder the terms: 4 + 4x + x2 = 1 + 4 Combine like terms: 1 + 4 = 5 4 + 4x + x2 = 5 Factor a perfect square on the left side: (x + 2)(x + 2) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (x + 2) equal to 2.236067978 and -2.236067978.Subproblem 1
x + 2 = 2.236067978 Simplifying x + 2 = 2.236067978 Reorder the terms: 2 + x = 2.236067978 Solving 2 + x = 2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 2.236067978 + -2 Combine like terms: 2 + -2 = 0 0 + x = 2.236067978 + -2 x = 2.236067978 + -2 Combine like terms: 2.236067978 + -2 = 0.236067978 x = 0.236067978 Simplifying x = 0.236067978Subproblem 2
x + 2 = -2.236067978 Simplifying x + 2 = -2.236067978 Reorder the terms: 2 + x = -2.236067978 Solving 2 + x = -2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -2.236067978 + -2 Combine like terms: 2 + -2 = 0 0 + x = -2.236067978 + -2 x = -2.236067978 + -2 Combine like terms: -2.236067978 + -2 = -4.236067978 x = -4.236067978 Simplifying x = -4.236067978Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.236067978, -4.236067978}
