Simplifying -10x2 + -9x = -8 Reorder the terms: -9x + -10x2 = -8 Solving -9x + -10x2 = -8 Solving for variable 'x'. Reorder the terms: 8 + -9x + -10x2 = -8 + 8 Combine like terms: -8 + 8 = 0 8 + -9x + -10x2 = 0 Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -0.8 + 0.9x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + 0.9x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + 0.9x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 0.9x + x2 = 0 + 0.8 0.9x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 0.9x + x2 = 0.8 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 = 0.8 + 0.2025 Reorder the terms: 0.2025 + 0.9x + x2 = 0.8 + 0.2025 Combine like terms: 0.8 + 0.2025 = 1.0025 0.2025 + 0.9x + x2 = 1.0025 Factor a perfect square on the left side: (x + 0.45)(x + 0.45) = 1.0025 Calculate the square root of the right side: 1.00124922 Break this problem into two subproblems by setting (x + 0.45) equal to 1.00124922 and -1.00124922.Subproblem 1
x + 0.45 = 1.00124922 Simplifying x + 0.45 = 1.00124922 Reorder the terms: 0.45 + x = 1.00124922 Solving 0.45 + x = 1.00124922 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 = 1.00124922 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = 1.00124922 + -0.45 x = 1.00124922 + -0.45 Combine like terms: 1.00124922 + -0.45 = 0.55124922 x = 0.55124922 Simplifying x = 0.55124922Subproblem 2
x + 0.45 = -1.00124922 Simplifying x + 0.45 = -1.00124922 Reorder the terms: 0.45 + x = -1.00124922 Solving 0.45 + x = -1.00124922 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 = -1.00124922 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = -1.00124922 + -0.45 x = -1.00124922 + -0.45 Combine like terms: -1.00124922 + -0.45 = -1.45124922 x = -1.45124922 Simplifying x = -1.45124922Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.55124922, -1.45124922}
