Simplifying 8x2 + 9x + -8 = 0 Reorder the terms: -8 + 9x + 8x2 = 0 Solving -8 + 9x + 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 + 1.125x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 1.125x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 1.125x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 1.125x + x2 = 0 + 1 1.125x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 1.125x + x2 = 1 The x term is 1.125x. Take half its coefficient (0.5625). Square it (0.31640625) and add it to both sides. Add '0.31640625' to each side of the equation. 1.125x + 0.31640625 + x2 = 1 + 0.31640625 Reorder the terms: 0.31640625 + 1.125x + x2 = 1 + 0.31640625 Combine like terms: 1 + 0.31640625 = 1.31640625 0.31640625 + 1.125x + x2 = 1.31640625 Factor a perfect square on the left side: (x + 0.5625)(x + 0.5625) = 1.31640625 Calculate the square root of the right side: 1.147347484 Break this problem into two subproblems by setting (x + 0.5625) equal to 1.147347484 and -1.147347484.Subproblem 1
x + 0.5625 = 1.147347484 Simplifying x + 0.5625 = 1.147347484 Reorder the terms: 0.5625 + x = 1.147347484 Solving 0.5625 + x = 1.147347484 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5625' to each side of the equation. 0.5625 + -0.5625 + x = 1.147347484 + -0.5625 Combine like terms: 0.5625 + -0.5625 = 0.0000 0.0000 + x = 1.147347484 + -0.5625 x = 1.147347484 + -0.5625 Combine like terms: 1.147347484 + -0.5625 = 0.584847484 x = 0.584847484 Simplifying x = 0.584847484Subproblem 2
x + 0.5625 = -1.147347484 Simplifying x + 0.5625 = -1.147347484 Reorder the terms: 0.5625 + x = -1.147347484 Solving 0.5625 + x = -1.147347484 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5625' to each side of the equation. 0.5625 + -0.5625 + x = -1.147347484 + -0.5625 Combine like terms: 0.5625 + -0.5625 = 0.0000 0.0000 + x = -1.147347484 + -0.5625 x = -1.147347484 + -0.5625 Combine like terms: -1.147347484 + -0.5625 = -1.709847484 x = -1.709847484 Simplifying x = -1.709847484Solution
