Simplifying x2 + 8x = 256 Reorder the terms: 8x + x2 = 256 Solving 8x + x2 = 256 Solving for variable 'x'. Reorder the terms: -256 + 8x + x2 = 256 + -256 Combine like terms: 256 + -256 = 0 -256 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '256' to each side of the equation. -256 + 8x + 256 + x2 = 0 + 256 Reorder the terms: -256 + 256 + 8x + x2 = 0 + 256 Combine like terms: -256 + 256 = 0 0 + 8x + x2 = 0 + 256 8x + x2 = 0 + 256 Combine like terms: 0 + 256 = 256 8x + x2 = 256 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 = 256 + 16 Reorder the terms: 16 + 8x + x2 = 256 + 16 Combine like terms: 256 + 16 = 272 16 + 8x + x2 = 272 Factor a perfect square on the left side: (x + 4)(x + 4) = 272 Calculate the square root of the right side: 16.492422502 Break this problem into two subproblems by setting (x + 4) equal to 16.492422502 and -16.492422502.Subproblem 1
x + 4 = 16.492422502 Simplifying x + 4 = 16.492422502 Reorder the terms: 4 + x = 16.492422502 Solving 4 + x = 16.492422502 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 = 16.492422502 + -4 Combine like terms: 4 + -4 = 0 0 + x = 16.492422502 + -4 x = 16.492422502 + -4 Combine like terms: 16.492422502 + -4 = 12.492422502 x = 12.492422502 Simplifying x = 12.492422502Subproblem 2
