Simplifying -8X2 + 3X + 9 = 0 Reorder the terms: 9 + 3X + -8X2 = 0 Solving 9 + 3X + -8X2 = 0 Solving for variable 'X'. Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -1.125 + -0.375X + X2 = 0 Move the constant term to the right: Add '1.125' to each side of the equation. -1.125 + -0.375X + 1.125 + X2 = 0 + 1.125 Reorder the terms: -1.125 + 1.125 + -0.375X + X2 = 0 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + -0.375X + X2 = 0 + 1.125 -0.375X + X2 = 0 + 1.125 Combine like terms: 0 + 1.125 = 1.125 -0.375X + X2 = 1.125 The X term is -0.375X. Take half its coefficient (-0.1875). Square it (0.03515625) and add it to both sides. Add '0.03515625' to each side of the equation. -0.375X + 0.03515625 + X2 = 1.125 + 0.03515625 Reorder the terms: 0.03515625 + -0.375X + X2 = 1.125 + 0.03515625 Combine like terms: 1.125 + 0.03515625 = 1.16015625 0.03515625 + -0.375X + X2 = 1.16015625 Factor a perfect square on the left side: (X + -0.1875)(X + -0.1875) = 1.16015625 Calculate the square root of the right side: 1.077105496 Break this problem into two subproblems by setting (X + -0.1875) equal to 1.077105496 and -1.077105496.Subproblem 1
X + -0.1875 = 1.077105496 Simplifying X + -0.1875 = 1.077105496 Reorder the terms: -0.1875 + X = 1.077105496 Solving -0.1875 + X = 1.077105496 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '0.1875' to each side of the equation. -0.1875 + 0.1875 + X = 1.077105496 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.0000 + X = 1.077105496 + 0.1875 X = 1.077105496 + 0.1875 Combine like terms: 1.077105496 + 0.1875 = 1.264605496 X = 1.264605496 Simplifying X = 1.264605496Subproblem 2
X + -0.1875 = -1.077105496 Simplifying X + -0.1875 = -1.077105496 Reorder the terms: -0.1875 + X = -1.077105496 Solving -0.1875 + X = -1.077105496 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '0.1875' to each side of the equation. -0.1875 + 0.1875 + X = -1.077105496 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.0000 + X = -1.077105496 + 0.1875 X = -1.077105496 + 0.1875 Combine like terms: -1.077105496 + 0.1875 = -0.889605496 X = -0.889605496 Simplifying X = -0.889605496Solution
