Simplifying 0.5x2 + 5x + -1 = 0 Reorder the terms: -1 + 5x + 0.5x2 = 0 Solving -1 + 5x + 0.5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. -2 + 10x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 10x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 10x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 10x + x2 = 0 + 2 10x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 10x + x2 = 2 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = 2 + 25 Reorder the terms: 25 + 10x + x2 = 2 + 25 Combine like terms: 2 + 25 = 27 25 + 10x + x2 = 27 Factor a perfect square on the left side: (x + 5)(x + 5) = 27 Calculate the square root of the right side: 5.196152423 Break this problem into two subproblems by setting (x + 5) equal to 5.196152423 and -5.196152423.Subproblem 1
x + 5 = 5.196152423 Simplifying x + 5 = 5.196152423 Reorder the terms: 5 + x = 5.196152423 Solving 5 + x = 5.196152423 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
