Simplifying -3x2 + 3x = -1 Reorder the terms: 3x + -3x2 = -1 Solving 3x + -3x2 = -1 Solving for variable 'x'. Reorder the terms: 1 + 3x + -3x2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + 3x + -3x2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. -0.3333333333 + -1x + x2 = 0 Move the constant term to the right: Add '0.3333333333' to each side of the equation. -0.3333333333 + -1x + 0.3333333333 + x2 = 0 + 0.3333333333 Reorder the terms: -0.3333333333 + 0.3333333333 + -1x + x2 = 0 + 0.3333333333 Combine like terms: -0.3333333333 + 0.3333333333 = 0.0000000000 0.0000000000 + -1x + x2 = 0 + 0.3333333333 -1x + x2 = 0 + 0.3333333333 Combine like terms: 0 + 0.3333333333 = 0.3333333333 -1x + x2 = 0.3333333333 The x term is -1x. 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. -1x + 0.25 + x2 = 0.3333333333 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 0.3333333333 + 0.25 Combine like terms: 0.3333333333 + 0.25 = 0.5833333333 0.25 + -1x + x2 = 0.5833333333 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 0.5833333333 Calculate the square root of the right side: 0.763762616 Break this problem into two subproblems by setting (x + -0.5) equal to 0.763762616 and -0.763762616.Subproblem 1
x + -0.5 = 0.763762616 Simplifying x + -0.5 = 0.763762616 Reorder the terms: -0.5 + x = 0.763762616 Solving -0.5 + x = 0.763762616 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 = 0.763762616 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 0.763762616 + 0.5 x = 0.763762616 + 0.5 Combine like terms: 0.763762616 + 0.5 = 1.263762616 x = 1.263762616 Simplifying x = 1.263762616Subproblem 2
x + -0.5 = -0.763762616 Simplifying x + -0.5 = -0.763762616 Reorder the terms: -0.5 + x = -0.763762616 Solving -0.5 + x = -0.763762616 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 = -0.763762616 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -0.763762616 + 0.5 x = -0.763762616 + 0.5 Combine like terms: -0.763762616 + 0.5 = -0.263762616 x = -0.263762616 Simplifying x = -0.263762616Solution
