Simplifying 16x2 + 1x + -1 = 0 Reorder the terms: -1 + 1x + 16x2 = 0 Solving -1 + 1x + 16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.0625 + 0.0625x + x2 = 0 Move the constant term to the right: Add '0.0625' to each side of the equation. -0.0625 + 0.0625x + 0.0625 + x2 = 0 + 0.0625 Reorder the terms: -0.0625 + 0.0625 + 0.0625x + x2 = 0 + 0.0625 Combine like terms: -0.0625 + 0.0625 = 0.0000 0.0000 + 0.0625x + x2 = 0 + 0.0625 0.0625x + x2 = 0 + 0.0625 Combine like terms: 0 + 0.0625 = 0.0625 0.0625x + x2 = 0.0625 The x term is 0.0625x. Take half its coefficient (0.03125). Square it (0.0009765625) and add it to both sides. Add '0.0009765625' to each side of the equation. 0.0625x + 0.0009765625 + x2 = 0.0625 + 0.0009765625 Reorder the terms: 0.0009765625 + 0.0625x + x2 = 0.0625 + 0.0009765625 Combine like terms: 0.0625 + 0.0009765625 = 0.0634765625 0.0009765625 + 0.0625x + x2 = 0.0634765625 Factor a perfect square on the left side: (x + 0.03125)(x + 0.03125) = 0.0634765625 Calculate the square root of the right side: 0.251945555 Break this problem into two subproblems by setting (x + 0.03125) equal to 0.251945555 and -0.251945555.Subproblem 1
x + 0.03125 = 0.251945555 Simplifying x + 0.03125 = 0.251945555 Reorder the terms: 0.03125 + x = 0.251945555 Solving 0.03125 + x = 0.251945555 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.03125' to each side of the equation. 0.03125 + -0.03125 + x = 0.251945555 + -0.03125 Combine like terms: 0.03125 + -0.03125 = 0.00000 0.00000 + x = 0.251945555 + -0.03125 x = 0.251945555 + -0.03125 Combine like terms: 0.251945555 + -0.03125 = 0.220695555 x = 0.220695555 Simplifying x = 0.220695555Subproblem 2
x + 0.03125 = -0.251945555 Simplifying x + 0.03125 = -0.251945555 Reorder the terms: 0.03125 + x = -0.251945555 Solving 0.03125 + x = -0.251945555 Solving for variable 'x'.
