Simplifying x2 + -8x = -1 Reorder the terms: -8x + x2 = -1 Solving -8x + x2 = -1 Solving for variable 'x'. Reorder the terms: 1 + -8x + x2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -8x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -8x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -8x + x2 = 0 + -1 -8x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -8x + x2 = -1 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 = -1 + 16 Reorder the terms: 16 + -8x + x2 = -1 + 16 Combine like terms: -1 + 16 = 15 16 + -8x + x2 = 15 Factor a perfect square on the left side: (x + -4)(x + -4) = 15 Calculate the square root of the right side: 3.872983346 Break this problem into two subproblems by setting (x + -4) equal to 3.872983346 and -3.872983346.Subproblem 1
x + -4 = 3.872983346 Simplifying x + -4 = 3.872983346 Reorder the terms: -4 + x = 3.872983346 Solving -4 + x = 3.872983346 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 = 3.872983346 + 4 Combine like terms: -4 + 4 = 0 0 + x = 3.872983346 + 4 x = 3.872983346 + 4 Combine like terms: 3.872983346 + 4 = 7.872983346 x = 7.872983346 Simplifying x = 7.872983346Subproblem 2
