Simplifying 5x2 + x + -0.5 = 0 Reorder the terms: -0.5 + x + 5x2 = 0 Solving -0.5 + x + 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'. -0.1 + 0.2x + x2 = 0 Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + 0.2x + 0.1 + x2 = 0 + 0.1 Reorder the terms: -0.1 + 0.1 + 0.2x + x2 = 0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + 0.2x + x2 = 0 + 0.1 0.2x + x2 = 0 + 0.1 Combine like terms: 0 + 0.1 = 0.1 0.2x + x2 = 0.1 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.2x + 0.25 + x2 = 0.1 + 0.25 Reorder the terms: 0.25 + 0.2x + x2 = 0.1 + 0.25 Combine like terms: 0.1 + 0.25 = 0.35 0.25 + 0.2x + x2 = 0.35 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.35 Calculate the square root of the right side: 0.591607978 Break this problem into two subproblems by setting (x + 0.5) equal to 0.591607978 and -0.591607978.Subproblem 1
x + 0.5 = 0.591607978 Simplifying x + 0.5 = 0.591607978 Reorder the terms: 0.5 + x = 0.591607978 Solving 0.5 + x = 0.591607978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 0.591607978 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.591607978 + -0.5 x = 0.591607978 + -0.5 Combine like terms: 0.591607978 + -0.5 = 0.091607978 x = 0.091607978 Simplifying x = 0.091607978Subproblem 2
x + 0.5 = -0.591607978 Simplifying x + 0.5 = -0.591607978 Reorder the terms: 0.5 + x = -0.591607978 Solving 0.5 + x = -0.591607978 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -0.591607978 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.591607978 + -0.5 x = -0.591607978 + -0.5 Combine like terms: -0.591607978 + -0.5 = -1.091607978 x = -1.091607978 Simplifying x = -1.091607978Solution
