Simplifying 8x2 + -18x + 7 = 2 Reorder the terms: 7 + -18x + 8x2 = 2 Solving 7 + -18x + 8x2 = 2 Solving for variable 'x'. Reorder the terms: 7 + -2 + -18x + 8x2 = 2 + -2 Combine like terms: 7 + -2 = 5 5 + -18x + 8x2 = 2 + -2 Combine like terms: 2 + -2 = 0 5 + -18x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.625 + -2.25x + x2 = 0 Move the constant term to the right: Add '-0.625' to each side of the equation. 0.625 + -2.25x + -0.625 + x2 = 0 + -0.625 Reorder the terms: 0.625 + -0.625 + -2.25x + x2 = 0 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + -2.25x + x2 = 0 + -0.625 -2.25x + x2 = 0 + -0.625 Combine like terms: 0 + -0.625 = -0.625 -2.25x + x2 = -0.625 The x term is -2.25x. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25x + 1.265625 + x2 = -0.625 + 1.265625 Reorder the terms: 1.265625 + -2.25x + x2 = -0.625 + 1.265625 Combine like terms: -0.625 + 1.265625 = 0.640625 1.265625 + -2.25x + x2 = 0.640625 Factor a perfect square on the left side: (x + -1.125)(x + -1.125) = 0.640625 Calculate the square root of the right side: 0.80039053 Break this problem into two subproblems by setting (x + -1.125) equal to 0.80039053 and -0.80039053.Subproblem 1
x + -1.125 = 0.80039053 Simplifying x + -1.125 = 0.80039053 Reorder the terms: -1.125 + x = 0.80039053 Solving -1.125 + x = 0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = 0.80039053 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = 0.80039053 + 1.125 x = 0.80039053 + 1.125 Combine like terms: 0.80039053 + 1.125 = 1.92539053 x = 1.92539053 Simplifying x = 1.92539053Subproblem 2
x + -1.125 = -0.80039053 Simplifying x + -1.125 = -0.80039053 Reorder the terms: -1.125 + x = -0.80039053 Solving -1.125 + x = -0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = -0.80039053 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = -0.80039053 + 1.125 x = -0.80039053 + 1.125 Combine like terms: -0.80039053 + 1.125 = 0.32460947 x = 0.32460947 Simplifying x = 0.32460947Solution
