Simplifying x2 + 4x + -8 = 5 Reorder the terms: -8 + 4x + x2 = 5 Solving -8 + 4x + x2 = 5 Solving for variable 'x'. Reorder the terms: -8 + -5 + 4x + x2 = 5 + -5 Combine like terms: -8 + -5 = -13 -13 + 4x + x2 = 5 + -5 Combine like terms: 5 + -5 = 0 -13 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '13' to each side of the equation. -13 + 4x + 13 + x2 = 0 + 13 Reorder the terms: -13 + 13 + 4x + x2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + 4x + x2 = 0 + 13 4x + x2 = 0 + 13 Combine like terms: 0 + 13 = 13 4x + x2 = 13 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 = 13 + 4 Reorder the terms: 4 + 4x + x2 = 13 + 4 Combine like terms: 13 + 4 = 17 4 + 4x + x2 = 17 Factor a perfect square on the left side: (x + 2)(x + 2) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (x + 2) equal to 4.123105626 and -4.123105626.Subproblem 1
x + 2 = 4.123105626 Simplifying x + 2 = 4.123105626 Reorder the terms: 2 + x = 4.123105626 Solving 2 + x = 4.123105626 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 = 4.123105626 + -2 Combine like terms: 2 + -2 = 0 0 + x = 4.123105626 + -2 x = 4.123105626 + -2 Combine like terms: 4.123105626 + -2 = 2.123105626 x = 2.123105626 Simplifying x = 2.123105626Subproblem 2
x + 2 = -4.123105626 Simplifying x + 2 = -4.123105626 Reorder the terms: 2 + x = -4.123105626 Solving 2 + x = -4.123105626 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 = -4.123105626 + -2 Combine like terms: 2 + -2 = 0 0 + x = -4.123105626 + -2 x = -4.123105626 + -2 Combine like terms: -4.123105626 + -2 = -6.123105626 x = -6.123105626 Simplifying x = -6.123105626Solution
