Simplifying 4x2 + 36x + -5 = 0 Reorder the terms: -5 + 36x + 4x2 = 0 Solving -5 + 36x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.25 + 9x + x2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + 9x + 1.25 + x2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + 9x + x2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + 9x + x2 = 0 + 1.25 9x + x2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 9x + x2 = 1.25 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 1.25 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 1.25 + 20.25 Combine like terms: 1.25 + 20.25 = 21.5 20.25 + 9x + x2 = 21.5 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 21.5 Calculate the square root of the right side: 4.636809248 Break this problem into two subproblems by setting (x + 4.5) equal to 4.636809248 and -4.636809248.Subproblem 1
x + 4.5 = 4.636809248 Simplifying x + 4.5 = 4.636809248 Reorder the terms: 4.5 + x = 4.636809248 Solving 4.5 + x = 4.636809248 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 4.636809248 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 4.636809248 + -4.5 x = 4.636809248 + -4.5 Combine like terms: 4.636809248 + -4.5 = 0.136809248 x = 0.136809248 Simplifying x = 0.136809248Subproblem 2
x + 4.5 = -4.636809248 Simplifying x + 4.5 = -4.636809248 Reorder the terms: 4.5 + x = -4.636809248 Solving 4.5 + x = -4.636809248 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -4.636809248 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -4.636809248 + -4.5 x = -4.636809248 + -4.5 Combine like terms: -4.636809248 + -4.5 = -9.136809248 x = -9.136809248 Simplifying x = -9.136809248Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.136809248, -9.136809248}
