Simplifying 20x2 + 2x + -1 = 0 Reorder the terms: -1 + 2x + 20x2 = 0 Solving -1 + 2x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -0.05 + 0.1x + x2 = 0 Move the constant term to the right: Add '0.05' to each side of the equation. -0.05 + 0.1x + 0.05 + x2 = 0 + 0.05 Reorder the terms: -0.05 + 0.05 + 0.1x + x2 = 0 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + 0.1x + x2 = 0 + 0.05 0.1x + x2 = 0 + 0.05 Combine like terms: 0 + 0.05 = 0.05 0.1x + x2 = 0.05 The x term is 0.1x. Take half its coefficient (0.05). Square it (0.0025) and add it to both sides. Add '0.0025' to each side of the equation. 0.1x + 0.0025 + x2 = 0.05 + 0.0025 Reorder the terms: 0.0025 + 0.1x + x2 = 0.05 + 0.0025 Combine like terms: 0.05 + 0.0025 = 0.0525 0.0025 + 0.1x + x2 = 0.0525 Factor a perfect square on the left side: (x + 0.05)(x + 0.05) = 0.0525 Calculate the square root of the right side: 0.229128785 Break this problem into two subproblems by setting (x + 0.05) equal to 0.229128785 and -0.229128785.Subproblem 1
x + 0.05 = 0.229128785 Simplifying x + 0.05 = 0.229128785 Reorder the terms: 0.05 + x = 0.229128785 Solving 0.05 + x = 0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = 0.229128785 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = 0.229128785 + -0.05 x = 0.229128785 + -0.05 Combine like terms: 0.229128785 + -0.05 = 0.179128785 x = 0.179128785 Simplifying x = 0.179128785Subproblem 2
x + 0.05 = -0.229128785 Simplifying x + 0.05 = -0.229128785 Reorder the terms: 0.05 + x = -0.229128785 Solving 0.05 + x = -0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = -0.229128785 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = -0.229128785 + -0.05 x = -0.229128785 + -0.05 Combine like terms: -0.229128785 + -0.05 = -0.279128785 x = -0.279128785 Simplifying x = -0.279128785Solution
