Simplifying -16x2 + 50x + 10 = 0 Reorder the terms: 10 + 50x + -16x2 = 0 Solving 10 + 50x + -16x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(5 + 25x + -8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(5 + 25x + -8x2)' equal to zero and attempt to solve: Simplifying 5 + 25x + -8x2 = 0 Solving 5 + 25x + -8x2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -0.625 + -3.125x + x2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -3.125x + 0.625 + x2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -3.125x + x2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -3.125x + x2 = 0 + 0.625 -3.125x + x2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -3.125x + x2 = 0.625 The x term is -3.125x. Take half its coefficient (-1.5625). Square it (2.44140625) and add it to both sides. Add '2.44140625' to each side of the equation. -3.125x + 2.44140625 + x2 = 0.625 + 2.44140625 Reorder the terms: 2.44140625 + -3.125x + x2 = 0.625 + 2.44140625 Combine like terms: 0.625 + 2.44140625 = 3.06640625 2.44140625 + -3.125x + x2 = 3.06640625 Factor a perfect square on the left side: (x + -1.5625)(x + -1.5625) = 3.06640625 Calculate the square root of the right side: 1.751115716 Break this problem into two subproblems by setting (x + -1.5625) equal to 1.751115716 and -1.751115716.Subproblem 1
x + -1.5625 = 1.751115716 Simplifying x + -1.5625 = 1.751115716 Reorder the terms: -1.5625 + x = 1.751115716 Solving -1.5625 + x = 1.751115716 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5625' to each side of the equation. -1.5625 + 1.5625 + x = 1.751115716 + 1.5625 Combine like terms: -1.5625 + 1.5625 = 0.0000 0.0000 + x = 1.751115716 + 1.5625 x = 1.751115716 + 1.5625 Combine like terms: 1.751115716 + 1.5625 = 3.313615716 x = 3.313615716 Simplifying x = 3.313615716Subproblem 2
x + -1.5625 = -1.751115716 Simplifying x + -1.5625 = -1.751115716 Reorder the terms: -1.5625 + x = -1.751115716 Solving -1.5625 + x = -1.751115716 Solving for variable 'x'.
