Simplifying 10x2 + 9x + -14 = 0 Reorder the terms: -14 + 9x + 10x2 = 0 Solving -14 + 9x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -1.4 + 0.9x + x2 = 0 Move the constant term to the right: Add '1.4' to each side of the equation. -1.4 + 0.9x + 1.4 + x2 = 0 + 1.4 Reorder the terms: -1.4 + 1.4 + 0.9x + x2 = 0 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + 0.9x + x2 = 0 + 1.4 0.9x + x2 = 0 + 1.4 Combine like terms: 0 + 1.4 = 1.4 0.9x + x2 = 1.4 The x term is 0.9x. Take half its coefficient (0.45). Square it (0.2025) and add it to both sides. Add '0.2025' to each side of the equation. 0.9x + 0.2025 + x2 = 1.4 + 0.2025 Reorder the terms: 0.2025 + 0.9x + x2 = 1.4 + 0.2025 Combine like terms: 1.4 + 0.2025 = 1.6025 0.2025 + 0.9x + x2 = 1.6025 Factor a perfect square on the left side: (x + 0.45)(x + 0.45) = 1.6025 Calculate the square root of the right side: 1.26589889 Break this problem into two subproblems by setting (x + 0.45) equal to 1.26589889 and -1.26589889.Subproblem 1
x + 0.45 = 1.26589889 Simplifying x + 0.45 = 1.26589889 Reorder the terms: 0.45 + x = 1.26589889 Solving 0.45 + x = 1.26589889 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.45' to each side of the equation. 0.45 + -0.45 + x = 1.26589889 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = 1.26589889 + -0.45 x = 1.26589889 + -0.45 Combine like terms: 1.26589889 + -0.45 = 0.81589889 x = 0.81589889 Simplifying x = 0.81589889Subproblem 2
x + 0.45 = -1.26589889 Simplifying x + 0.45 = -1.26589889 Reorder the terms: 0.45 + x = -1.26589889 Solving 0.45 + x = -1.26589889 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.45' to each side of the equation. 0.45 + -0.45 + x = -1.26589889 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = -1.26589889 + -0.45 x = -1.26589889 + -0.45 Combine like terms: -1.26589889 + -0.45 = -1.71589889 x = -1.71589889 Simplifying x = -1.71589889Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.81589889, -1.71589889}
