Simplifying 8x = 5x2 + -2 Reorder the terms: 8x = -2 + 5x2 Solving 8x = -2 + 5x2 Solving for variable 'x'. Reorder the terms: 2 + 8x + -5x2 = -2 + 5x2 + 2 + -5x2 Reorder the terms: 2 + 8x + -5x2 = -2 + 2 + 5x2 + -5x2 Combine like terms: -2 + 2 = 0 2 + 8x + -5x2 = 0 + 5x2 + -5x2 2 + 8x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 2 + 8x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -0.4 + -1.6x + x2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + -1.6x + 0.4 + x2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + -1.6x + x2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + -1.6x + x2 = 0 + 0.4 -1.6x + x2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 -1.6x + x2 = 0.4 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = 0.4 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = 0.4 + 0.64 Combine like terms: 0.4 + 0.64 = 1.04 0.64 + -1.6x + x2 = 1.04 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 1.04 Calculate the square root of the right side: 1.019803903 Break this problem into two subproblems by setting (x + -0.8) equal to 1.019803903 and -1.019803903.Subproblem 1
x + -0.8 = 1.019803903 Simplifying x + -0.8 = 1.019803903 Reorder the terms: -0.8 + x = 1.019803903 Solving -0.8 + x = 1.019803903 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 1.019803903 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 1.019803903 + 0.8 x = 1.019803903 + 0.8 Combine like terms: 1.019803903 + 0.8 = 1.819803903 x = 1.819803903 Simplifying x = 1.819803903Subproblem 2
x + -0.8 = -1.019803903 Simplifying x + -0.8 = -1.019803903 Reorder the terms: -0.8 + x = -1.019803903 Solving -0.8 + x = -1.019803903 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -1.019803903 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -1.019803903 + 0.8 x = -1.019803903 + 0.8 Combine like terms: -1.019803903 + 0.8 = -0.219803903 x = -0.219803903 Simplifying x = -0.219803903Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.819803903, -0.219803903}
