Simplifying x2 + 0.6x + -0.05 = 0 Reorder the terms: -0.05 + 0.6x + x2 = 0 Solving -0.05 + 0.6x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '0.05' to each side of the equation. -0.05 + 0.6x + 0.05 + x2 = 0 + 0.05 Reorder the terms: -0.05 + 0.05 + 0.6x + x2 = 0 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + 0.6x + x2 = 0 + 0.05 0.6x + x2 = 0 + 0.05 Combine like terms: 0 + 0.05 = 0.05 0.6x + x2 = 0.05 The x term is 0.6x. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6x + 0.09 + x2 = 0.05 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = 0.05 + 0.09 Combine like terms: 0.05 + 0.09 = 0.14 0.09 + 0.6x + x2 = 0.14 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = 0.14 Calculate the square root of the right side: 0.374165739 Break this problem into two subproblems by setting (x + 0.3) equal to 0.374165739 and -0.374165739.Subproblem 1
x + 0.3 = 0.374165739 Simplifying x + 0.3 = 0.374165739 Reorder the terms: 0.3 + x = 0.374165739 Solving 0.3 + x = 0.374165739 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = 0.374165739 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 0.374165739 + -0.3 x = 0.374165739 + -0.3 Combine like terms: 0.374165739 + -0.3 = 0.074165739 x = 0.074165739 Simplifying x = 0.074165739Subproblem 2
x + 0.3 = -0.374165739 Simplifying x + 0.3 = -0.374165739 Reorder the terms: 0.3 + x = -0.374165739 Solving 0.3 + x = -0.374165739 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = -0.374165739 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -0.374165739 + -0.3 x = -0.374165739 + -0.3 Combine like terms: -0.374165739 + -0.3 = -0.674165739 x = -0.674165739 Simplifying x = -0.674165739Solution
