Simplifying x2 + 10x + 7 = 2x + -4 Reorder the terms: 7 + 10x + x2 = 2x + -4 Reorder the terms: 7 + 10x + x2 = -4 + 2x Solving 7 + 10x + x2 = -4 + 2x Solving for variable 'x'. Reorder the terms: 7 + 4 + 10x + -2x + x2 = -4 + 2x + 4 + -2x Combine like terms: 7 + 4 = 11 11 + 10x + -2x + x2 = -4 + 2x + 4 + -2x Combine like terms: 10x + -2x = 8x 11 + 8x + x2 = -4 + 2x + 4 + -2x Reorder the terms: 11 + 8x + x2 = -4 + 4 + 2x + -2x Combine like terms: -4 + 4 = 0 11 + 8x + x2 = 0 + 2x + -2x 11 + 8x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 11 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + 8x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + 8x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + 8x + x2 = 0 + -11 8x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 8x + x2 = -11 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = -11 + 16 Reorder the terms: 16 + 8x + x2 = -11 + 16 Combine like terms: -11 + 16 = 5 16 + 8x + x2 = 5 Factor a perfect square on the left side: (x + 4)(x + 4) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (x + 4) equal to 2.236067978 and -2.236067978.Subproblem 1
x + 4 = 2.236067978 Simplifying x + 4 = 2.236067978 Reorder the terms: 4 + x = 2.236067978 Solving 4 + x = 2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 2.236067978 + -4 Combine like terms: 4 + -4 = 0 0 + x = 2.236067978 + -4 x = 2.236067978 + -4 Combine like terms: 2.236067978 + -4 = -1.763932022 x = -1.763932022 Simplifying x = -1.763932022Subproblem 2
x + 4 = -2.236067978 Simplifying x + 4 = -2.236067978 Reorder the terms: 4 + x = -2.236067978 Solving 4 + x = -2.236067978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -2.236067978 + -4 Combine like terms: 4 + -4 = 0 0 + x = -2.236067978 + -4 x = -2.236067978 + -4 Combine like terms: -2.236067978 + -4 = -6.236067978 x = -6.236067978 Simplifying x = -6.236067978Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.763932022, -6.236067978}
