Simplifying 8x2 + 16x + -42 = 1 Reorder the terms: -42 + 16x + 8x2 = 1 Solving -42 + 16x + 8x2 = 1 Solving for variable 'x'. Reorder the terms: -42 + -1 + 16x + 8x2 = 1 + -1 Combine like terms: -42 + -1 = -43 -43 + 16x + 8x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -43 + 16x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -5.375 + 2x + x2 = 0 Move the constant term to the right: Add '5.375' to each side of the equation. -5.375 + 2x + 5.375 + x2 = 0 + 5.375 Reorder the terms: -5.375 + 5.375 + 2x + x2 = 0 + 5.375 Combine like terms: -5.375 + 5.375 = 0.000 0.000 + 2x + x2 = 0 + 5.375 2x + x2 = 0 + 5.375 Combine like terms: 0 + 5.375 = 5.375 2x + x2 = 5.375 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 5.375 + 1 Reorder the terms: 1 + 2x + x2 = 5.375 + 1 Combine like terms: 5.375 + 1 = 6.375 1 + 2x + x2 = 6.375 Factor a perfect square on the left side: (x + 1)(x + 1) = 6.375 Calculate the square root of the right side: 2.524876235 Break this problem into two subproblems by setting (x + 1) equal to 2.524876235 and -2.524876235.Subproblem 1
x + 1 = 2.524876235 Simplifying x + 1 = 2.524876235 Reorder the terms: 1 + x = 2.524876235 Solving 1 + x = 2.524876235 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 2.524876235 + -1 Combine like terms: 1 + -1 = 0 0 + x = 2.524876235 + -1 x = 2.524876235 + -1 Combine like terms: 2.524876235 + -1 = 1.524876235 x = 1.524876235 Simplifying x = 1.524876235Subproblem 2
x + 1 = -2.524876235 Simplifying x + 1 = -2.524876235 Reorder the terms: 1 + x = -2.524876235 Solving 1 + x = -2.524876235 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -2.524876235 + -1 Combine like terms: 1 + -1 = 0 0 + x = -2.524876235 + -1 x = -2.524876235 + -1 Combine like terms: -2.524876235 + -1 = -3.524876235 x = -3.524876235 Simplifying x = -3.524876235Solution
