Simplifying 5x2 + 20x + 8 = 0 Reorder the terms: 8 + 20x + 5x2 = 0 Solving 8 + 20x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.6 + 4x + x2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + 4x + -1.6 + x2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + 4x + x2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + 4x + x2 = 0 + -1.6 4x + x2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 4x + x2 = -1.6 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = -1.6 + 4 Reorder the terms: 4 + 4x + x2 = -1.6 + 4 Combine like terms: -1.6 + 4 = 2.4 4 + 4x + x2 = 2.4 Factor a perfect square on the left side: (x + 2)(x + 2) = 2.4 Calculate the square root of the right side: 1.549193338 Break this problem into two subproblems by setting (x + 2) equal to 1.549193338 and -1.549193338.Subproblem 1
x + 2 = 1.549193338 Simplifying x + 2 = 1.549193338 Reorder the terms: 2 + x = 1.549193338 Solving 2 + x = 1.549193338 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 1.549193338 + -2 Combine like terms: 2 + -2 = 0 0 + x = 1.549193338 + -2 x = 1.549193338 + -2 Combine like terms: 1.549193338 + -2 = -0.450806662 x = -0.450806662 Simplifying x = -0.450806662Subproblem 2
x + 2 = -1.549193338 Simplifying x + 2 = -1.549193338 Reorder the terms: 2 + x = -1.549193338 Solving 2 + x = -1.549193338 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -1.549193338 + -2 Combine like terms: 2 + -2 = 0 0 + x = -1.549193338 + -2 x = -1.549193338 + -2 Combine like terms: -1.549193338 + -2 = -3.549193338 x = -3.549193338 Simplifying x = -3.549193338Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.450806662, -3.549193338}
