Simplifying 10x2 + -9x + -12 = 0 Reorder the terms: -12 + -9x + 10x2 = 0 Solving -12 + -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'. -1.2 + -0.9x + x2 = 0 Move the constant term to the right: Add '1.2' to each side of the equation. -1.2 + -0.9x + 1.2 + x2 = 0 + 1.2 Reorder the terms: -1.2 + 1.2 + -0.9x + x2 = 0 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + -0.9x + x2 = 0 + 1.2 -0.9x + x2 = 0 + 1.2 Combine like terms: 0 + 1.2 = 1.2 -0.9x + x2 = 1.2 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 = 1.2 + 0.2025 Reorder the terms: 0.2025 + -0.9x + x2 = 1.2 + 0.2025 Combine like terms: 1.2 + 0.2025 = 1.4025 0.2025 + -0.9x + x2 = 1.4025 Factor a perfect square on the left side: (x + -0.45)(x + -0.45) = 1.4025 Calculate the square root of the right side: 1.184271928 Break this problem into two subproblems by setting (x + -0.45) equal to 1.184271928 and -1.184271928.Subproblem 1
x + -0.45 = 1.184271928 Simplifying x + -0.45 = 1.184271928 Reorder the terms: -0.45 + x = 1.184271928 Solving -0.45 + x = 1.184271928 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 = 1.184271928 + 0.45 Combine like terms: -0.45 + 0.45 = 0.00 0.00 + x = 1.184271928 + 0.45 x = 1.184271928 + 0.45 Combine like terms: 1.184271928 + 0.45 = 1.634271928 x = 1.634271928 Simplifying x = 1.634271928Subproblem 2
x + -0.45 = -1.184271928 Simplifying x + -0.45 = -1.184271928 Reorder the terms: -0.45 + x = -1.184271928 Solving -0.45 + x = -1.184271928 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 = -1.184271928 + 0.45 Combine like terms: -0.45 + 0.45 = 0.00 0.00 + x = -1.184271928 + 0.45 x = -1.184271928 + 0.45 Combine like terms: -1.184271928 + 0.45 = -0.734271928 x = -0.734271928 Simplifying x = -0.734271928Solution
