Simplifying 15x2 + 6x + -2 = 0 Reorder the terms: -2 + 6x + 15x2 = 0 Solving -2 + 6x + 15x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 15 the coefficient of the squared term: Divide each side by '15'. -0.1333333333 + 0.4x + x2 = 0 Move the constant term to the right: Add '0.1333333333' to each side of the equation. -0.1333333333 + 0.4x + 0.1333333333 + x2 = 0 + 0.1333333333 Reorder the terms: -0.1333333333 + 0.1333333333 + 0.4x + x2 = 0 + 0.1333333333 Combine like terms: -0.1333333333 + 0.1333333333 = 0.0000000000 0.0000000000 + 0.4x + x2 = 0 + 0.1333333333 0.4x + x2 = 0 + 0.1333333333 Combine like terms: 0 + 0.1333333333 = 0.1333333333 0.4x + x2 = 0.1333333333 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = 0.1333333333 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = 0.1333333333 + 0.04 Combine like terms: 0.1333333333 + 0.04 = 0.1733333333 0.04 + 0.4x + x2 = 0.1733333333 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = 0.1733333333 Calculate the square root of the right side: 0.4163332 Break this problem into two subproblems by setting (x + 0.2) equal to 0.4163332 and -0.4163332.Subproblem 1
x + 0.2 = 0.4163332 Simplifying x + 0.2 = 0.4163332 Reorder the terms: 0.2 + x = 0.4163332 Solving 0.2 + x = 0.4163332 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = 0.4163332 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = 0.4163332 + -0.2 x = 0.4163332 + -0.2 Combine like terms: 0.4163332 + -0.2 = 0.2163332 x = 0.2163332 Simplifying x = 0.2163332Subproblem 2
x + 0.2 = -0.4163332 Simplifying x + 0.2 = -0.4163332 Reorder the terms: 0.2 + x = -0.4163332 Solving 0.2 + x = -0.4163332 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = -0.4163332 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = -0.4163332 + -0.2 x = -0.4163332 + -0.2 Combine like terms: -0.4163332 + -0.2 = -0.6163332 x = -0.6163332 Simplifying x = -0.6163332Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.2163332, -0.6163332}
