Simplifying 9x2 + 45x + 38 = 0 Reorder the terms: 38 + 45x + 9x2 = 0 Solving 38 + 45x + 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'. 4.222222222 + 5x + x2 = 0 Move the constant term to the right: Add '-4.222222222' to each side of the equation. 4.222222222 + 5x + -4.222222222 + x2 = 0 + -4.222222222 Reorder the terms: 4.222222222 + -4.222222222 + 5x + x2 = 0 + -4.222222222 Combine like terms: 4.222222222 + -4.222222222 = 0.000000000 0.000000000 + 5x + x2 = 0 + -4.222222222 5x + x2 = 0 + -4.222222222 Combine like terms: 0 + -4.222222222 = -4.222222222 5x + x2 = -4.222222222 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = -4.222222222 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -4.222222222 + 6.25 Combine like terms: -4.222222222 + 6.25 = 2.027777778 6.25 + 5x + x2 = 2.027777778 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 2.027777778 Calculate the square root of the right side: 1.424000624 Break this problem into two subproblems by setting (x + 2.5) equal to 1.424000624 and -1.424000624.Subproblem 1
x + 2.5 = 1.424000624 Simplifying x + 2.5 = 1.424000624 Reorder the terms: 2.5 + x = 1.424000624 Solving 2.5 + x = 1.424000624 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 1.424000624 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 1.424000624 + -2.5 x = 1.424000624 + -2.5 Combine like terms: 1.424000624 + -2.5 = -1.075999376 x = -1.075999376 Simplifying x = -1.075999376Subproblem 2
x + 2.5 = -1.424000624 Simplifying x + 2.5 = -1.424000624 Reorder the terms: 2.5 + x = -1.424000624 Solving 2.5 + x = -1.424000624 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -1.424000624 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -1.424000624 + -2.5 x = -1.424000624 + -2.5 Combine like terms: -1.424000624 + -2.5 = -3.924000624 x = -3.924000624 Simplifying x = -3.924000624Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.075999376, -3.924000624}
