Simplifying 64 + 64 + 16x + x2 = 256 Combine like terms: 64 + 64 = 128 128 + 16x + x2 = 256 Solving 128 + 16x + x2 = 256 Solving for variable 'x'. Reorder the terms: 128 + -256 + 16x + x2 = 256 + -256 Combine like terms: 128 + -256 = -128 -128 + 16x + x2 = 256 + -256 Combine like terms: 256 + -256 = 0 -128 + 16x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '128' to each side of the equation. -128 + 16x + 128 + x2 = 0 + 128 Reorder the terms: -128 + 128 + 16x + x2 = 0 + 128 Combine like terms: -128 + 128 = 0 0 + 16x + x2 = 0 + 128 16x + x2 = 0 + 128 Combine like terms: 0 + 128 = 128 16x + x2 = 128 The x term is 16x. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16x + 64 + x2 = 128 + 64 Reorder the terms: 64 + 16x + x2 = 128 + 64 Combine like terms: 128 + 64 = 192 64 + 16x + x2 = 192 Factor a perfect square on the left side: (x + 8)(x + 8) = 192 Calculate the square root of the right side: 13.856406461 Break this problem into two subproblems by setting (x + 8) equal to 13.856406461 and -13.856406461.Subproblem 1
x + 8 = 13.856406461 Simplifying x + 8 = 13.856406461 Reorder the terms: 8 + x = 13.856406461 Solving 8 + x = 13.856406461 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = 13.856406461 + -8 Combine like terms: 8 + -8 = 0 0 + x = 13.856406461 + -8 x = 13.856406461 + -8 Combine like terms: 13.856406461 + -8 = 5.856406461 x = 5.856406461 Simplifying x = 5.856406461Subproblem 2
x + 8 = -13.856406461 Simplifying x + 8 = -13.856406461 Reorder the terms: 8 + x = -13.856406461 Solving 8 + x = -13.856406461 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = -13.856406461 + -8 Combine like terms: 8 + -8 = 0 0 + x = -13.856406461 + -8 x = -13.856406461 + -8 Combine like terms: -13.856406461 + -8 = -21.856406461 x = -21.856406461 Simplifying x = -21.856406461Solution
