Simplifying 2x2 + 17x + -4 = 0 Reorder the terms: -4 + 17x + 2x2 = 0 Solving -4 + 17x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2 + 8.5x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 8.5x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 8.5x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 8.5x + x2 = 0 + 2 8.5x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 8.5x + x2 = 2 The x term is 8.5x. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5x + 18.0625 + x2 = 2 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = 2 + 18.0625 Combine like terms: 2 + 18.0625 = 20.0625 18.0625 + 8.5x + x2 = 20.0625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 20.0625 Calculate the square root of the right side: 4.479118217 Break this problem into two subproblems by setting (x + 4.25) equal to 4.479118217 and -4.479118217.Subproblem 1
x + 4.25 = 4.479118217 Simplifying x + 4.25 = 4.479118217 Reorder the terms: 4.25 + x = 4.479118217 Solving 4.25 + x = 4.479118217 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = 4.479118217 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 4.479118217 + -4.25 x = 4.479118217 + -4.25 Combine like terms: 4.479118217 + -4.25 = 0.229118217 x = 0.229118217 Simplifying x = 0.229118217Subproblem 2
x + 4.25 = -4.479118217 Simplifying x + 4.25 = -4.479118217 Reorder the terms: 4.25 + x = -4.479118217 Solving 4.25 + x = -4.479118217 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + x = -4.479118217 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = -4.479118217 + -4.25 x = -4.479118217 + -4.25 Combine like terms: -4.479118217 + -4.25 = -8.729118217 x = -8.729118217 Simplifying x = -8.729118217Solution
