Simplifying -4x2 + 2x = -1 Reorder the terms: 2x + -4x2 = -1 Solving 2x + -4x2 = -1 Solving for variable 'x'. Reorder the terms: 1 + 2x + -4x2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + 2x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.25 + -0.5x + x2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + -0.5x + 0.25 + x2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + -0.5x + x2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + -0.5x + x2 = 0 + 0.25 -0.5x + x2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 -0.5x + x2 = 0.25 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 0.25 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 0.25 + 0.0625 Combine like terms: 0.25 + 0.0625 = 0.3125 0.0625 + -0.5x + x2 = 0.3125 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 0.3125 Calculate the square root of the right side: 0.559016994 Break this problem into two subproblems by setting (x + -0.25) equal to 0.559016994 and -0.559016994.Subproblem 1
x + -0.25 = 0.559016994 Simplifying x + -0.25 = 0.559016994 Reorder the terms: -0.25 + x = 0.559016994 Solving -0.25 + x = 0.559016994 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 0.559016994 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 0.559016994 + 0.25 x = 0.559016994 + 0.25 Combine like terms: 0.559016994 + 0.25 = 0.809016994 x = 0.809016994 Simplifying x = 0.809016994Subproblem 2
x + -0.25 = -0.559016994 Simplifying x + -0.25 = -0.559016994 Reorder the terms: -0.25 + x = -0.559016994 Solving -0.25 + x = -0.559016994 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -0.559016994 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -0.559016994 + 0.25 x = -0.559016994 + 0.25 Combine like terms: -0.559016994 + 0.25 = -0.309016994 x = -0.309016994 Simplifying x = -0.309016994Solution
