Simplifying 4x2 + -8 = x Reorder the terms: -8 + 4x2 = x Solving -8 + 4x2 = x Solving for variable 'x'. Reorder the terms: -8 + -1x + 4x2 = x + -1x Combine like terms: x + -1x = 0 -8 + -1x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2 + -0.25x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + -0.25x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + -0.25x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -0.25x + x2 = 0 + 2 -0.25x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -0.25x + x2 = 2 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = 2 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 2 + 0.015625 Combine like terms: 2 + 0.015625 = 2.015625 0.015625 + -0.25x + x2 = 2.015625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 2.015625 Calculate the square root of the right side: 1.419727086 Break this problem into two subproblems by setting (x + -0.125) equal to 1.419727086 and -1.419727086.Subproblem 1
x + -0.125 = 1.419727086 Simplifying x + -0.125 = 1.419727086 Reorder the terms: -0.125 + x = 1.419727086 Solving -0.125 + x = 1.419727086 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = 1.419727086 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 1.419727086 + 0.125 x = 1.419727086 + 0.125 Combine like terms: 1.419727086 + 0.125 = 1.544727086 x = 1.544727086 Simplifying x = 1.544727086Subproblem 2
x + -0.125 = -1.419727086 Simplifying x + -0.125 = -1.419727086 Reorder the terms: -0.125 + x = -1.419727086 Solving -0.125 + x = -1.419727086 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = -1.419727086 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -1.419727086 + 0.125 x = -1.419727086 + 0.125 Combine like terms: -1.419727086 + 0.125 = -1.294727086 x = -1.294727086 Simplifying x = -1.294727086Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.544727086, -1.294727086}
