Simplifying 2x2 + 17x + 18 = 0 Reorder the terms: 18 + 17x + 2x2 = 0 Solving 18 + 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'. 9 + 8.5x + x2 = 0 Move the constant term to the right: Add '-9' to each side of the equation. 9 + 8.5x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + 8.5x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 8.5x + x2 = 0 + -9 8.5x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 8.5x + x2 = -9 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 = -9 + 18.0625 Reorder the terms: 18.0625 + 8.5x + x2 = -9 + 18.0625 Combine like terms: -9 + 18.0625 = 9.0625 18.0625 + 8.5x + x2 = 9.0625 Factor a perfect square on the left side: (x + 4.25)(x + 4.25) = 9.0625 Calculate the square root of the right side: 3.010398645 Break this problem into two subproblems by setting (x + 4.25) equal to 3.010398645 and -3.010398645.Subproblem 1
x + 4.25 = 3.010398645 Simplifying x + 4.25 = 3.010398645 Reorder the terms: 4.25 + x = 3.010398645 Solving 4.25 + x = 3.010398645 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 = 3.010398645 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = 3.010398645 + -4.25 x = 3.010398645 + -4.25 Combine like terms: 3.010398645 + -4.25 = -1.239601355 x = -1.239601355 Simplifying x = -1.239601355Subproblem 2
x + 4.25 = -3.010398645 Simplifying x + 4.25 = -3.010398645 Reorder the terms: 4.25 + x = -3.010398645 Solving 4.25 + x = -3.010398645 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 = -3.010398645 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x = -3.010398645 + -4.25 x = -3.010398645 + -4.25 Combine like terms: -3.010398645 + -4.25 = -7.260398645 x = -7.260398645 Simplifying x = -7.260398645Solution
