Simplifying -16x2 + 24x + 3 = 0 Reorder the terms: 3 + 24x + -16x2 = 0 Solving 3 + 24x + -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'. -0.1875 + -1.5x + x2 = 0 Move the constant term to the right: Add '0.1875' to each side of the equation. -0.1875 + -1.5x + 0.1875 + x2 = 0 + 0.1875 Reorder the terms: -0.1875 + 0.1875 + -1.5x + x2 = 0 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.0000 + -1.5x + x2 = 0 + 0.1875 -1.5x + x2 = 0 + 0.1875 Combine like terms: 0 + 0.1875 = 0.1875 -1.5x + x2 = 0.1875 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 0.1875 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 0.1875 + 0.5625 Combine like terms: 0.1875 + 0.5625 = 0.75 0.5625 + -1.5x + x2 = 0.75 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 0.75 Calculate the square root of the right side: 0.866025404 Break this problem into two subproblems by setting (x + -0.75) equal to 0.866025404 and -0.866025404.Subproblem 1
x + -0.75 = 0.866025404 Simplifying x + -0.75 = 0.866025404 Reorder the terms: -0.75 + x = 0.866025404 Solving -0.75 + x = 0.866025404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 0.866025404 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 0.866025404 + 0.75 x = 0.866025404 + 0.75 Combine like terms: 0.866025404 + 0.75 = 1.616025404 x = 1.616025404 Simplifying x = 1.616025404Subproblem 2
x + -0.75 = -0.866025404 Simplifying x + -0.75 = -0.866025404 Reorder the terms: -0.75 + x = -0.866025404 Solving -0.75 + x = -0.866025404 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -0.866025404 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -0.866025404 + 0.75 x = -0.866025404 + 0.75 Combine like terms: -0.866025404 + 0.75 = -0.116025404 x = -0.116025404 Simplifying x = -0.116025404Solution
