Simplifying 12x2 + -15x + -1 = 0 Reorder the terms: -1 + -15x + 12x2 = 0 Solving -1 + -15x + 12x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. -0.08333333333 + -1.25x + x2 = 0 Move the constant term to the right: Add '0.08333333333' to each side of the equation. -0.08333333333 + -1.25x + 0.08333333333 + x2 = 0 + 0.08333333333 Reorder the terms: -0.08333333333 + 0.08333333333 + -1.25x + x2 = 0 + 0.08333333333 Combine like terms: -0.08333333333 + 0.08333333333 = 0.00000000000 0.00000000000 + -1.25x + x2 = 0 + 0.08333333333 -1.25x + x2 = 0 + 0.08333333333 Combine like terms: 0 + 0.08333333333 = 0.08333333333 -1.25x + x2 = 0.08333333333 The x term is -1.25x. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25x + 0.390625 + x2 = 0.08333333333 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = 0.08333333333 + 0.390625 Combine like terms: 0.08333333333 + 0.390625 = 0.47395833333 0.390625 + -1.25x + x2 = 0.47395833333 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = 0.47395833333 Calculate the square root of the right side: 0.688446318 Break this problem into two subproblems by setting (x + -0.625) equal to 0.688446318 and -0.688446318.Subproblem 1
x + -0.625 = 0.688446318 Simplifying x + -0.625 = 0.688446318 Reorder the terms: -0.625 + x = 0.688446318 Solving -0.625 + x = 0.688446318 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = 0.688446318 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = 0.688446318 + 0.625 x = 0.688446318 + 0.625 Combine like terms: 0.688446318 + 0.625 = 1.313446318 x = 1.313446318 Simplifying x = 1.313446318Subproblem 2
x + -0.625 = -0.688446318 Simplifying x + -0.625 = -0.688446318 Reorder the terms: -0.625 + x = -0.688446318 Solving -0.625 + x = -0.688446318 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = -0.688446318 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = -0.688446318 + 0.625 x = -0.688446318 + 0.625 Combine like terms: -0.688446318 + 0.625 = -0.063446318 x = -0.063446318 Simplifying x = -0.063446318Solution
