Simplifying 9x2 + 18x + -98 = -6 Reorder the terms: -98 + 18x + 9x2 = -6 Solving -98 + 18x + 9x2 = -6 Solving for variable 'x'. Reorder the terms: -98 + 6 + 18x + 9x2 = -6 + 6 Combine like terms: -98 + 6 = -92 -92 + 18x + 9x2 = -6 + 6 Combine like terms: -6 + 6 = 0 -92 + 18x + 9x2 = 0 Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. -10.22222222 + 2x + x2 = 0 Move the constant term to the right: Add '10.22222222' to each side of the equation. -10.22222222 + 2x + 10.22222222 + x2 = 0 + 10.22222222 Reorder the terms: -10.22222222 + 10.22222222 + 2x + x2 = 0 + 10.22222222 Combine like terms: -10.22222222 + 10.22222222 = 0.00000000 0.00000000 + 2x + x2 = 0 + 10.22222222 2x + x2 = 0 + 10.22222222 Combine like terms: 0 + 10.22222222 = 10.22222222 2x + x2 = 10.22222222 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 10.22222222 + 1 Reorder the terms: 1 + 2x + x2 = 10.22222222 + 1 Combine like terms: 10.22222222 + 1 = 11.22222222 1 + 2x + x2 = 11.22222222 Factor a perfect square on the left side: (x + 1)(x + 1) = 11.22222222 Calculate the square root of the right side: 3.34995854 Break this problem into two subproblems by setting (x + 1) equal to 3.34995854 and -3.34995854.Subproblem 1
x + 1 = 3.34995854 Simplifying x + 1 = 3.34995854 Reorder the terms: 1 + x = 3.34995854 Solving 1 + x = 3.34995854 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 3.34995854 + -1 Combine like terms: 1 + -1 = 0 0 + x = 3.34995854 + -1 x = 3.34995854 + -1 Combine like terms: 3.34995854 + -1 = 2.34995854 x = 2.34995854 Simplifying x = 2.34995854Subproblem 2
x + 1 = -3.34995854 Simplifying x + 1 = -3.34995854 Reorder the terms: 1 + x = -3.34995854 Solving 1 + x = -3.34995854 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -3.34995854 + -1 Combine like terms: 1 + -1 = 0 0 + x = -3.34995854 + -1 x = -3.34995854 + -1 Combine like terms: -3.34995854 + -1 = -4.34995854 x = -4.34995854 Simplifying x = -4.34995854Solution
