Simplifying 5x2 + 7x + -5 = 0 Reorder the terms: -5 + 7x + 5x2 = 0 Solving -5 + 7x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1 + 1.4x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 1.4x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 1.4x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 1.4x + x2 = 0 + 1 1.4x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 1.4x + x2 = 1 The x term is 1.4x. Take half its coefficient (0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. 1.4x + 0.49 + x2 = 1 + 0.49 Reorder the terms: 0.49 + 1.4x + x2 = 1 + 0.49 Combine like terms: 1 + 0.49 = 1.49 0.49 + 1.4x + x2 = 1.49 Factor a perfect square on the left side: (x + 0.7)(x + 0.7) = 1.49 Calculate the square root of the right side: 1.220655562 Break this problem into two subproblems by setting (x + 0.7) equal to 1.220655562 and -1.220655562.Subproblem 1
x + 0.7 = 1.220655562 Simplifying x + 0.7 = 1.220655562 Reorder the terms: 0.7 + x = 1.220655562 Solving 0.7 + x = 1.220655562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.7' to each side of the equation. 0.7 + -0.7 + x = 1.220655562 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + x = 1.220655562 + -0.7 x = 1.220655562 + -0.7 Combine like terms: 1.220655562 + -0.7 = 0.520655562 x = 0.520655562 Simplifying x = 0.520655562Subproblem 2
x + 0.7 = -1.220655562 Simplifying x + 0.7 = -1.220655562 Reorder the terms: 0.7 + x = -1.220655562 Solving 0.7 + x = -1.220655562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.7' to each side of the equation. 0.7 + -0.7 + x = -1.220655562 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + x = -1.220655562 + -0.7 x = -1.220655562 + -0.7 Combine like terms: -1.220655562 + -0.7 = -1.920655562 x = -1.920655562 Simplifying x = -1.920655562Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.520655562, -1.920655562}
