Simplifying 5x2 + 7x + -130 = 0 Reorder the terms: -130 + 7x + 5x2 = 0 Solving -130 + 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'. -26 + 1.4x + x2 = 0 Move the constant term to the right: Add '26' to each side of the equation. -26 + 1.4x + 26 + x2 = 0 + 26 Reorder the terms: -26 + 26 + 1.4x + x2 = 0 + 26 Combine like terms: -26 + 26 = 0 0 + 1.4x + x2 = 0 + 26 1.4x + x2 = 0 + 26 Combine like terms: 0 + 26 = 26 1.4x + x2 = 26 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 = 26 + 0.49 Reorder the terms: 0.49 + 1.4x + x2 = 26 + 0.49 Combine like terms: 26 + 0.49 = 26.49 0.49 + 1.4x + x2 = 26.49 Factor a perfect square on the left side: (x + 0.7)(x + 0.7) = 26.49 Calculate the square root of the right side: 5.146843693 Break this problem into two subproblems by setting (x + 0.7) equal to 5.146843693 and -5.146843693.Subproblem 1
x + 0.7 = 5.146843693 Simplifying x + 0.7 = 5.146843693 Reorder the terms: 0.7 + x = 5.146843693 Solving 0.7 + x = 5.146843693 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 = 5.146843693 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + x = 5.146843693 + -0.7 x = 5.146843693 + -0.7 Combine like terms: 5.146843693 + -0.7 = 4.446843693 x = 4.446843693 Simplifying x = 4.446843693Subproblem 2
x + 0.7 = -5.146843693 Simplifying x + 0.7 = -5.146843693 Reorder the terms: 0.7 + x = -5.146843693 Solving 0.7 + x = -5.146843693 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 = -5.146843693 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + x = -5.146843693 + -0.7 x = -5.146843693 + -0.7 Combine like terms: -5.146843693 + -0.7 = -5.846843693 x = -5.846843693 Simplifying x = -5.846843693Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.446843693, -5.846843693}
