Simplifying 8x2 + -9x = 1 Reorder the terms: -9x + 8x2 = 1 Solving -9x + 8x2 = 1 Solving for variable 'x'. Reorder the terms: -1 + -9x + 8x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + -9x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.125 + -1.125x + x2 = 0 Move the constant term to the right: Add '0.125' to each side of the equation. -0.125 + -1.125x + 0.125 + x2 = 0 + 0.125 Reorder the terms: -0.125 + 0.125 + -1.125x + x2 = 0 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + -1.125x + x2 = 0 + 0.125 -1.125x + x2 = 0 + 0.125 Combine like terms: 0 + 0.125 = 0.125 -1.125x + x2 = 0.125 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 = 0.125 + 0.31640625 Reorder the terms: 0.31640625 + -1.125x + x2 = 0.125 + 0.31640625 Combine like terms: 0.125 + 0.31640625 = 0.44140625 0.31640625 + -1.125x + x2 = 0.44140625 Factor a perfect square on the left side: (x + -0.5625)(x + -0.5625) = 0.44140625 Calculate the square root of the right side: 0.664384113 Break this problem into two subproblems by setting (x + -0.5625) equal to 0.664384113 and -0.664384113.Subproblem 1
x + -0.5625 = 0.664384113 Simplifying x + -0.5625 = 0.664384113 Reorder the terms: -0.5625 + x = 0.664384113 Solving -0.5625 + x = 0.664384113 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 = 0.664384113 + 0.5625 Combine like terms: -0.5625 + 0.5625 = 0.0000 0.0000 + x = 0.664384113 + 0.5625 x = 0.664384113 + 0.5625 Combine like terms: 0.664384113 + 0.5625 = 1.226884113 x = 1.226884113 Simplifying x = 1.226884113Subproblem 2
x + -0.5625 = -0.664384113 Simplifying x + -0.5625 = -0.664384113 Reorder the terms: -0.5625 + x = -0.664384113 Solving -0.5625 + x = -0.664384113 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
