Simplifying 2x2 + 17x + 29 = 0 Reorder the terms: 29 + 17x + 2x2 = 0 Solving 29 + 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'. 14.5 + 8.5x + x2 = 0 Move the constant term to the right: Add '-14.5' to each side of the equation. 14.5 + 8.5x + -14.5 + x2 = 0 + -14.5 Reorder the terms: 14.5 + -14.5 + 8.5x + x2 = 0 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + 8.5x + x2 = 0 + -14.5 8.5x + x2 = 0 + -14.5 Combine like terms: 0 + -14.5 = -14.5 8.5x + x2 = -14.5 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 = -14.5 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = -14.5 + 18.0625 Combine like terms: -14.5 + 18.0625 = 3.5625 18.0625 + 8.5x + x2 = 3.5625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (x + 4.25) equal to 1.887458609 and -1.887458609.Subproblem 1
x + 4.25 = 1.887458609 Simplifying x + 4.25 = 1.887458609 Reorder the terms: 4.25 + x = 1.887458609 Solving 4.25 + x = 1.887458609 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 = 1.887458609 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 1.887458609 + -4.25 x = 1.887458609 + -4.25 Combine like terms: 1.887458609 + -4.25 = -2.362541391 x = -2.362541391 Simplifying x = -2.362541391Subproblem 2
x + 4.25 = -1.887458609 Simplifying x + 4.25 = -1.887458609 Reorder the terms: 4.25 + x = -1.887458609 Solving 4.25 + x = -1.887458609 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
