Simplifying x2 + 4x + -92 = 9 Reorder the terms: -92 + 4x + x2 = 9 Solving -92 + 4x + x2 = 9 Solving for variable 'x'. Reorder the terms: -92 + -9 + 4x + x2 = 9 + -9 Combine like terms: -92 + -9 = -101 -101 + 4x + x2 = 9 + -9 Combine like terms: 9 + -9 = 0 -101 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '101' to each side of the equation. -101 + 4x + 101 + x2 = 0 + 101 Reorder the terms: -101 + 101 + 4x + x2 = 0 + 101 Combine like terms: -101 + 101 = 0 0 + 4x + x2 = 0 + 101 4x + x2 = 0 + 101 Combine like terms: 0 + 101 = 101 4x + x2 = 101 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 = 101 + 4 Reorder the terms: 4 + 4x + x2 = 101 + 4 Combine like terms: 101 + 4 = 105 4 + 4x + x2 = 105 Factor a perfect square on the left side: (x + 2)(x + 2) = 105 Calculate the square root of the right side: 10.246950766 Break this problem into two subproblems by setting (x + 2) equal to 10.246950766 and -10.246950766.Subproblem 1
x + 2 = 10.246950766 Simplifying x + 2 = 10.246950766 Reorder the terms: 2 + x = 10.246950766 Solving 2 + x = 10.246950766 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 = 10.246950766 + -2 Combine like terms: 2 + -2 = 0 0 + x = 10.246950766 + -2 x = 10.246950766 + -2 Combine like terms: 10.246950766 + -2 = 8.246950766 x = 8.246950766 Simplifying x = 8.246950766Subproblem 2
x + 2 = -10.246950766 Simplifying x + 2 = -10.246950766 Reorder the terms: 2 + x = -10.246950766 Solving 2 + x = -10.246950766 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 = -10.246950766 + -2 Combine like terms: 2 + -2 = 0 0 + x = -10.246950766 + -2 x = -10.246950766 + -2 Combine like terms: -10.246950766 + -2 = -12.246950766 x = -12.246950766 Simplifying x = -12.246950766Solution
