Subproblem 1

Set the factor '(2 + 8x + 5x2)' equal to zero and attempt to solve: Simplifying 2 + 8x + 5x2 = 0 Solving 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 = 0.24 0.64 + 1.6x + x2 = 0.24 Factor a perfect square on the left side: (x + 0.8)(x + 0.8) = 0.24 Calculate the square root of the right side: 0.489897949 Break this problem into two subproblems by setting (x + 0.8) equal to 0.489897949 and -0.489897949.

Subproblem 1

x + 0.8 = 0.489897949 Simplifying x + 0.8 = 0.489897949 Reorder the terms: 0.8 + x = 0.489897949 Solving 0.8 + x = 0.489897949 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 = 0.489897949 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = 0.489897949 + -0.8 x = 0.489897949 + -0.8 Combine like terms: 0.489897949 + -0.8 = -0.310102051 x = -0.310102051 Simplifying x = -0.310102051

Subproblem 2

x + 0.8 = -0.489897949 Simplifying x + 0.8 = -0.489897949 Reorder the terms: 0.8 + x = -0.489897949 Solving 0.8 + x = -0.489897949 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 = -0.489897949 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = -0.489897949 + -0.8 x = -0.489897949 + -0.8 Combine like terms: -0.489897949 + -0.8 = -1.289897949 x = -1.289897949 Simplifying x = -1.289897949
