Simplifying 2x = 5x2 + -8 Reorder the terms: 2x = -8 + 5x2 Solving 2x = -8 + 5x2 Solving for variable 'x'. Reorder the terms: 8 + 2x + -5x2 = -8 + 5x2 + 8 + -5x2 Reorder the terms: 8 + 2x + -5x2 = -8 + 8 + 5x2 + -5x2 Combine like terms: -8 + 8 = 0 8 + 2x + -5x2 = 0 + 5x2 + -5x2 8 + 2x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 8 + 2x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.6 + -0.4x + x2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + -0.4x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + -0.4x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + -0.4x + x2 = 0 + 1.6 -0.4x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 -0.4x + x2 = 1.6 The x term is -0.4x. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4x + 0.04 + x2 = 1.6 + 0.04 Reorder the terms: 0.04 + -0.4x + x2 = 1.6 + 0.04 Combine like terms: 1.6 + 0.04 = 1.64 0.04 + -0.4x + x2 = 1.64 Factor a perfect square on the left side: (x + -0.2)(x + -0.2) = 1.64 Calculate the square root of the right side: 1.280624847 Break this problem into two subproblems by setting (x + -0.2) equal to 1.280624847 and -1.280624847.Subproblem 1
x + -0.2 = 1.280624847 Simplifying x + -0.2 = 1.280624847 Reorder the terms: -0.2 + x = 1.280624847 Solving -0.2 + x = 1.280624847 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = 1.280624847 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = 1.280624847 + 0.2 x = 1.280624847 + 0.2 Combine like terms: 1.280624847 + 0.2 = 1.480624847 x = 1.480624847 Simplifying x = 1.480624847Subproblem 2
x + -0.2 = -1.280624847 Simplifying x + -0.2 = -1.280624847 Reorder the terms: -0.2 + x = -1.280624847 Solving -0.2 + x = -1.280624847 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = -1.280624847 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = -1.280624847 + 0.2 x = -1.280624847 + 0.2 Combine like terms: -1.280624847 + 0.2 = -1.080624847 x = -1.080624847 Simplifying x = -1.080624847Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.480624847, -1.080624847}
