Simplifying x2 + -2x + -4 = -3 + 9 Reorder the terms: -4 + -2x + x2 = -3 + 9 Combine like terms: -3 + 9 = 6 -4 + -2x + x2 = 6 Solving -4 + -2x + x2 = 6 Solving for variable 'x'. Reorder the terms: -4 + -6 + -2x + x2 = 6 + -6 Combine like terms: -4 + -6 = -10 -10 + -2x + x2 = 6 + -6 Combine like terms: 6 + -6 = 0 -10 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + -2x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -2x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -2x + x2 = 0 + 10 -2x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -2x + x2 = 10 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 = 10 + 1 Reorder the terms: 1 + -2x + x2 = 10 + 1 Combine like terms: 10 + 1 = 11 1 + -2x + x2 = 11 Factor a perfect square on the left side: (x + -1)(x + -1) = 11 Calculate the square root of the right side: 3.31662479 Break this problem into two subproblems by setting (x + -1) equal to 3.31662479 and -3.31662479.Subproblem 1
x + -1 = 3.31662479 Simplifying x + -1 = 3.31662479 Reorder the terms: -1 + x = 3.31662479 Solving -1 + x = 3.31662479 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 = 3.31662479 + 1 Combine like terms: -1 + 1 = 0 0 + x = 3.31662479 + 1 x = 3.31662479 + 1 Combine like terms: 3.31662479 + 1 = 4.31662479 x = 4.31662479 Simplifying x = 4.31662479Subproblem 2
x + -1 = -3.31662479 Simplifying x + -1 = -3.31662479 Reorder the terms: -1 + x = -3.31662479 Solving -1 + x = -3.31662479 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 = -3.31662479 + 1 Combine like terms: -1 + 1 = 0 0 + x = -3.31662479 + 1 x = -3.31662479 + 1 Combine like terms: -3.31662479 + 1 = -2.31662479 x = -2.31662479 Simplifying x = -2.31662479Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.31662479, -2.31662479}
