Simplifying x2 + 128x = 220 Reorder the terms: 128x + x2 = 220 Solving 128x + x2 = 220 Solving for variable 'x'. Reorder the terms: -220 + 128x + x2 = 220 + -220 Combine like terms: 220 + -220 = 0 -220 + 128x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '220' to each side of the equation. -220 + 128x + 220 + x2 = 0 + 220 Reorder the terms: -220 + 220 + 128x + x2 = 0 + 220 Combine like terms: -220 + 220 = 0 0 + 128x + x2 = 0 + 220 128x + x2 = 0 + 220 Combine like terms: 0 + 220 = 220 128x + x2 = 220 The x term is 128x. Take half its coefficient (64). Square it (4096) and add it to both sides. Add '4096' to each side of the equation. 128x + 4096 + x2 = 220 + 4096 Reorder the terms: 4096 + 128x + x2 = 220 + 4096 Combine like terms: 220 + 4096 = 4316 4096 + 128x + x2 = 4316 Factor a perfect square on the left side: (x + 64)(x + 64) = 4316 Calculate the square root of the right side: 65.696270823 Break this problem into two subproblems by setting (x + 64) equal to 65.696270823 and -65.696270823.Subproblem 1
x + 64 = 65.696270823 Simplifying x + 64 = 65.696270823 Reorder the terms: 64 + x = 65.696270823 Solving 64 + x = 65.696270823 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
