Simplifying 9x2 + 36x + 2 = 0 Reorder the terms: 2 + 36x + 9x2 = 0 Solving 2 + 36x + 9x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. 0.2222222222 + 4x + x2 = 0 Move the constant term to the right: Add '-0.2222222222' to each side of the equation. 0.2222222222 + 4x + -0.2222222222 + x2 = 0 + -0.2222222222 Reorder the terms: 0.2222222222 + -0.2222222222 + 4x + x2 = 0 + -0.2222222222 Combine like terms: 0.2222222222 + -0.2222222222 = 0.0000000000 0.0000000000 + 4x + x2 = 0 + -0.2222222222 4x + x2 = 0 + -0.2222222222 Combine like terms: 0 + -0.2222222222 = -0.2222222222 4x + x2 = -0.2222222222 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = -0.2222222222 + 4 Reorder the terms: 4 + 4x + x2 = -0.2222222222 + 4 Combine like terms: -0.2222222222 + 4 = 3.7777777778 4 + 4x + x2 = 3.7777777778 Factor a perfect square on the left side: (x + 2)(x + 2) = 3.7777777778 Calculate the square root of the right side: 1.943650632 Break this problem into two subproblems by setting (x + 2) equal to 1.943650632 and -1.943650632.Subproblem 1
x + 2 = 1.943650632 Simplifying x + 2 = 1.943650632 Reorder the terms: 2 + x = 1.943650632 Solving 2 + x = 1.943650632 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 1.943650632 + -2 Combine like terms: 2 + -2 = 0 0 + x = 1.943650632 + -2 x = 1.943650632 + -2 Combine like terms: 1.943650632 + -2 = -0.056349368 x = -0.056349368 Simplifying x = -0.056349368Subproblem 2
x + 2 = -1.943650632 Simplifying x + 2 = -1.943650632 Reorder the terms: 2 + x = -1.943650632 Solving 2 + x = -1.943650632 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -1.943650632 + -2 Combine like terms: 2 + -2 = 0 0 + x = -1.943650632 + -2 x = -1.943650632 + -2 Combine like terms: -1.943650632 + -2 = -3.943650632 x = -3.943650632 Simplifying x = -3.943650632Solution
