Simplifying 1 + 1.3x + 0.4x2 = 0 Solving 1 + 1.3x + 0.4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.4 the coefficient of the squared term: Divide each side by '0.4'. 2.5 + 3.25x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 3.25x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 3.25x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 3.25x + x2 = 0 + -2.5 3.25x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 3.25x + x2 = -2.5 The x term is 3.25x. Take half its coefficient (1.625). Square it (2.640625) and add it to both sides. Add '2.640625' to each side of the equation. 3.25x + 2.640625 + x2 = -2.5 + 2.640625 Reorder the terms: 2.640625 + 3.25x + x2 = -2.5 + 2.640625 Combine like terms: -2.5 + 2.640625 = 0.140625 2.640625 + 3.25x + x2 = 0.140625 Factor a perfect square on the left side: (x + 1.625)(x + 1.625) = 0.140625 Calculate the square root of the right side: 0.375 Break this problem into two subproblems by setting (x + 1.625) equal to 0.375 and -0.375.Subproblem 1
x + 1.625 = 0.375 Simplifying x + 1.625 = 0.375 Reorder the terms: 1.625 + x = 0.375 Solving 1.625 + x = 0.375 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.625' to each side of the equation. 1.625 + -1.625 + x = 0.375 + -1.625 Combine like terms: 1.625 + -1.625 = 0.000 0.000 + x = 0.375 + -1.625 x = 0.375 + -1.625 Combine like terms: 0.375 + -1.625 = -1.25 x = -1.25 Simplifying x = -1.25Subproblem 2
x + 1.625 = -0.375 Simplifying x + 1.625 = -0.375 Reorder the terms: 1.625 + x = -0.375 Solving 1.625 + x = -0.375 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.625' to each side of the equation. 1.625 + -1.625 + x = -0.375 + -1.625 Combine like terms: 1.625 + -1.625 = 0.000 0.000 + x = -0.375 + -1.625 x = -0.375 + -1.625 Combine like terms: -0.375 + -1.625 = -2 x = -2 Simplifying x = -2Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.25, -2}
