Simplifying -40x2 + -1x + -2 = 0 Reorder the terms: -2 + -1x + -40x2 = 0 Solving -2 + -1x + -40x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-1'. -1(2 + x + 40x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(2 + x + 40x2)' equal to zero and attempt to solve: Simplifying 2 + x + 40x2 = 0 Solving 2 + x + 40x2 = 0 Begin completing the square. Divide all terms by 40 the coefficient of the squared term: Divide each side by '40'. 0.05 + 0.025x + x2 = 0.0 Move the constant term to the right: Add '-0.05' to each side of the equation. 0.05 + 0.025x + -0.05 + x2 = 0.0 + -0.05 Reorder the terms: 0.05 + -0.05 + 0.025x + x2 = 0.0 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + 0.025x + x2 = 0.0 + -0.05 0.025x + x2 = 0.0 + -0.05 Combine like terms: 0.0 + -0.05 = -0.05 0.025x + x2 = -0.05 The x term is x. 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. 0.025x + 0.25 + x2 = -0.05 + 0.25 Reorder the terms: 0.25 + 0.025x + x2 = -0.05 + 0.25 Combine like terms: -0.05 + 0.25 = 0.2 0.25 + 0.025x + x2 = 0.2 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.2 Calculate the square root of the right side: 0.447213596 Break this problem into two subproblems by setting (x + 0.5) equal to 0.447213596 and -0.447213596.Subproblem 1
x + 0.5 = 0.447213596 Simplifying x + 0.5 = 0.447213596 Reorder the terms: 0.5 + x = 0.447213596 Solving 0.5 + x = 0.447213596 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 = 0.447213596 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.447213596 + -0.5 x = 0.447213596 + -0.5 Combine like terms: 0.447213596 + -0.5 = -0.052786404 x = -0.052786404 Simplifying x = -0.052786404Subproblem 2
x + 0.5 = -0.447213596 Simplifying x + 0.5 = -0.447213596 Reorder the terms: 0.5 + x = -0.447213596 Solving 0.5 + x = -0.447213596 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 = -0.447213596 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.447213596 + -0.5 x = -0.447213596 + -0.5 Combine like terms: -0.447213596 + -0.5 = -0.947213596 x = -0.947213596 Simplifying x = -0.947213596Solution
