Simplifying 47 = -16x2 + -4x + 64 Reorder the terms: 47 = 64 + -4x + -16x2 Solving 47 = 64 + -4x + -16x2 Solving for variable 'x'. Combine like terms: 47 + -64 = -17 -17 + 4x + 16x2 = 64 + -4x + -16x2 + -64 + 4x + 16x2 Reorder the terms: -17 + 4x + 16x2 = 64 + -64 + -4x + 4x + -16x2 + 16x2 Combine like terms: 64 + -64 = 0 -17 + 4x + 16x2 = 0 + -4x + 4x + -16x2 + 16x2 -17 + 4x + 16x2 = -4x + 4x + -16x2 + 16x2 Combine like terms: -4x + 4x = 0 -17 + 4x + 16x2 = 0 + -16x2 + 16x2 -17 + 4x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 -17 + 4x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -1.0625 + 0.25x + x2 = 0 Move the constant term to the right: Add '1.0625' to each side of the equation. -1.0625 + 0.25x + 1.0625 + x2 = 0 + 1.0625 Reorder the terms: -1.0625 + 1.0625 + 0.25x + x2 = 0 + 1.0625 Combine like terms: -1.0625 + 1.0625 = 0.0000 0.0000 + 0.25x + x2 = 0 + 1.0625 0.25x + x2 = 0 + 1.0625 Combine like terms: 0 + 1.0625 = 1.0625 0.25x + x2 = 1.0625 The x term is 0.25x. Take half its coefficient (0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. 0.25x + 0.015625 + x2 = 1.0625 + 0.015625 Reorder the terms: 0.015625 + 0.25x + x2 = 1.0625 + 0.015625 Combine like terms: 1.0625 + 0.015625 = 1.078125 0.015625 + 0.25x + x2 = 1.078125 Factor a perfect square on the left side: (x + 0.125)(x + 0.125) = 1.078125 Calculate the square root of the right side: 1.038327983 Break this problem into two subproblems by setting (x + 0.125) equal to 1.038327983 and -1.038327983.Subproblem 1
x + 0.125 = 1.038327983 Simplifying x + 0.125 = 1.038327983 Reorder the terms: 0.125 + x = 1.038327983 Solving 0.125 + x = 1.038327983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.125' to each side of the equation. 0.125 + -0.125 + x = 1.038327983 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + x = 1.038327983 + -0.125 x = 1.038327983 + -0.125 Combine like terms: 1.038327983 + -0.125 = 0.913327983 x = 0.913327983 Simplifying x = 0.913327983Subproblem 2
x + 0.125 = -1.038327983 Simplifying x + 0.125 = -1.038327983 Reorder the terms: 0.125 + x = -1.038327983 Solving 0.125 + x = -1.038327983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.125' to each side of the equation. 0.125 + -0.125 + x = -1.038327983 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + x = -1.038327983 + -0.125 x = -1.038327983 + -0.125 Combine like terms: -1.038327983 + -0.125 = -1.163327983 x = -1.163327983 Simplifying x = -1.163327983Solution
