Simplifying 5x2 + 16x + 2 = 0 Reorder the terms: 2 + 16x + 5x2 = 0 Solving 2 + 16x + 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'. 0.4 + 3.2x + x2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + 3.2x + -0.4 + x2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + 3.2x + x2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + 3.2x + x2 = 0 + -0.4 3.2x + x2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 3.2x + x2 = -0.4 The x term is 3.2x. Take half its coefficient (1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. 3.2x + 2.56 + x2 = -0.4 + 2.56 Reorder the terms: 2.56 + 3.2x + x2 = -0.4 + 2.56 Combine like terms: -0.4 + 2.56 = 2.16 2.56 + 3.2x + x2 = 2.16 Factor a perfect square on the left side: (x + 1.6)(x + 1.6) = 2.16 Calculate the square root of the right side: 1.469693846 Break this problem into two subproblems by setting (x + 1.6) equal to 1.469693846 and -1.469693846.Subproblem 1
x + 1.6 = 1.469693846 Simplifying x + 1.6 = 1.469693846 Reorder the terms: 1.6 + x = 1.469693846 Solving 1.6 + x = 1.469693846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = 1.469693846 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = 1.469693846 + -1.6 x = 1.469693846 + -1.6 Combine like terms: 1.469693846 + -1.6 = -0.130306154 x = -0.130306154 Simplifying x = -0.130306154Subproblem 2
x + 1.6 = -1.469693846 Simplifying x + 1.6 = -1.469693846 Reorder the terms: 1.6 + x = -1.469693846 Solving 1.6 + x = -1.469693846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = -1.469693846 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = -1.469693846 + -1.6 x = -1.469693846 + -1.6 Combine like terms: -1.469693846 + -1.6 = -3.069693846 x = -3.069693846 Simplifying x = -3.069693846Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.130306154, -3.069693846}
