Simplifying -16x2 + 4x + 26 = 0 Reorder the terms: 26 + 4x + -16x2 = 0 Solving 26 + 4x + -16x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(13 + 2x + -8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(13 + 2x + -8x2)' equal to zero and attempt to solve: Simplifying 13 + 2x + -8x2 = 0 Solving 13 + 2x + -8x2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -1.625 + -0.25x + x2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + -0.25x + 1.625 + x2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + -0.25x + x2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + -0.25x + x2 = 0 + 1.625 -0.25x + x2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 -0.25x + x2 = 1.625 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 = 1.625 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 1.625 + 0.015625 Combine like terms: 1.625 + 0.015625 = 1.640625 0.015625 + -0.25x + x2 = 1.640625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 1.640625 Calculate the square root of the right side: 1.280868846 Break this problem into two subproblems by setting (x + -0.125) equal to 1.280868846 and -1.280868846.Subproblem 1
x + -0.125 = 1.280868846 Simplifying x + -0.125 = 1.280868846 Reorder the terms: -0.125 + x = 1.280868846 Solving -0.125 + x = 1.280868846 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 = 1.280868846 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 1.280868846 + 0.125 x = 1.280868846 + 0.125 Combine like terms: 1.280868846 + 0.125 = 1.405868846 x = 1.405868846 Simplifying x = 1.405868846Subproblem 2
x + -0.125 = -1.280868846 Simplifying x + -0.125 = -1.280868846 Reorder the terms: -0.125 + x = -1.280868846 Solving -0.125 + x = -1.280868846 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 = -1.280868846 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -1.280868846 + 0.125 x = -1.280868846 + 0.125 Combine like terms: -1.280868846 + 0.125 = -1.155868846 x = -1.155868846 Simplifying x = -1.155868846Solution
