Simplifying -1x2 + 2.1x = -0.2 Reorder the terms: 2.1x + -1x2 = -0.2 Solving 2.1x + -1x2 = -0.2 Solving for variable 'x'. Reorder the terms: 0.2 + 2.1x + -1x2 = -0.2 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.2 + 2.1x + -1x2 = 0.0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -0.2 + -2.1x + x2 = 0.0 Move the constant term to the right: Add '0.2' to each side of the equation. -0.2 + -2.1x + 0.2 + x2 = 0.0 + 0.2 Reorder the terms: -0.2 + 0.2 + -2.1x + x2 = 0.0 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + -2.1x + x2 = 0.0 + 0.2 -2.1x + x2 = 0.0 + 0.2 Combine like terms: 0.0 + 0.2 = 0.2 -2.1x + x2 = 0.2 The x term is -2.1x. Take half its coefficient (-1.05). Square it (1.1025) and add it to both sides. Add '1.1025' to each side of the equation. -2.1x + 1.1025 + x2 = 0.2 + 1.1025 Reorder the terms: 1.1025 + -2.1x + x2 = 0.2 + 1.1025 Combine like terms: 0.2 + 1.1025 = 1.3025 1.1025 + -2.1x + x2 = 1.3025 Factor a perfect square on the left side: (x + -1.05)(x + -1.05) = 1.3025 Calculate the square root of the right side: 1.141271221 Break this problem into two subproblems by setting (x + -1.05) equal to 1.141271221 and -1.141271221.Subproblem 1
x + -1.05 = 1.141271221 Simplifying x + -1.05 = 1.141271221 Reorder the terms: -1.05 + x = 1.141271221 Solving -1.05 + x = 1.141271221 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.05' to each side of the equation. -1.05 + 1.05 + x = 1.141271221 + 1.05 Combine like terms: -1.05 + 1.05 = 0.00 0.00 + x = 1.141271221 + 1.05 x = 1.141271221 + 1.05 Combine like terms: 1.141271221 + 1.05 = 2.191271221 x = 2.191271221 Simplifying x = 2.191271221Subproblem 2
x + -1.05 = -1.141271221 Simplifying x + -1.05 = -1.141271221 Reorder the terms: -1.05 + x = -1.141271221 Solving -1.05 + x = -1.141271221 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.05' to each side of the equation. -1.05 + 1.05 + x = -1.141271221 + 1.05 Combine like terms: -1.05 + 1.05 = 0.00 0.00 + x = -1.141271221 + 1.05 x = -1.141271221 + 1.05 Combine like terms: -1.141271221 + 1.05 = -0.091271221 x = -0.091271221 Simplifying x = -0.091271221Solution
