Simplifying 8x2 + -7x + 1 = 0 Reorder the terms: 1 + -7x + 8x2 = 0 Solving 1 + -7x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.125 + -0.875x + x2 = 0 Move the constant term to the right: Add '-0.125' to each side of the equation. 0.125 + -0.875x + -0.125 + x2 = 0 + -0.125 Reorder the terms: 0.125 + -0.125 + -0.875x + x2 = 0 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + -0.875x + x2 = 0 + -0.125 -0.875x + x2 = 0 + -0.125 Combine like terms: 0 + -0.125 = -0.125 -0.875x + x2 = -0.125 The x term is -0.875x. Take half its coefficient (-0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. -0.875x + 0.19140625 + x2 = -0.125 + 0.19140625 Reorder the terms: 0.19140625 + -0.875x + x2 = -0.125 + 0.19140625 Combine like terms: -0.125 + 0.19140625 = 0.06640625 0.19140625 + -0.875x + x2 = 0.06640625 Factor a perfect square on the left side: (x + -0.4375)(x + -0.4375) = 0.06640625 Calculate the square root of the right side: 0.257694102 Break this problem into two subproblems by setting (x + -0.4375) equal to 0.257694102 and -0.257694102.Subproblem 1
x + -0.4375 = 0.257694102 Simplifying x + -0.4375 = 0.257694102 Reorder the terms: -0.4375 + x = 0.257694102 Solving -0.4375 + x = 0.257694102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4375' to each side of the equation. -0.4375 + 0.4375 + x = 0.257694102 + 0.4375 Combine like terms: -0.4375 + 0.4375 = 0.0000 0.0000 + x = 0.257694102 + 0.4375 x = 0.257694102 + 0.4375 Combine like terms: 0.257694102 + 0.4375 = 0.695194102 x = 0.695194102 Simplifying x = 0.695194102Subproblem 2
x + -0.4375 = -0.257694102 Simplifying x + -0.4375 = -0.257694102 Reorder the terms: -0.4375 + x = -0.257694102 Solving -0.4375 + x = -0.257694102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4375' to each side of the equation. -0.4375 + 0.4375 + x = -0.257694102 + 0.4375 Combine like terms: -0.4375 + 0.4375 = 0.0000 0.0000 + x = -0.257694102 + 0.4375 x = -0.257694102 + 0.4375 Combine like terms: -0.257694102 + 0.4375 = 0.179805898 x = 0.179805898 Simplifying x = 0.179805898Solution
