Simplifying x2 + 9x + -380 = 0 Reorder the terms: -380 + 9x + x2 = 0 Solving -380 + 9x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '380' to each side of the equation. -380 + 9x + 380 + x2 = 0 + 380 Reorder the terms: -380 + 380 + 9x + x2 = 0 + 380 Combine like terms: -380 + 380 = 0 0 + 9x + x2 = 0 + 380 9x + x2 = 0 + 380 Combine like terms: 0 + 380 = 380 9x + x2 = 380 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 = 380 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 380 + 20.25 Combine like terms: 380 + 20.25 = 400.25 20.25 + 9x + x2 = 400.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 400.25 Calculate the square root of the right side: 20.006249024 Break this problem into two subproblems by setting (x + 4.5) equal to 20.006249024 and -20.006249024.Subproblem 1
x + 4.5 = 20.006249024 Simplifying x + 4.5 = 20.006249024 Reorder the terms: 4.5 + x = 20.006249024 Solving 4.5 + x = 20.006249024 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 = 20.006249024 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 20.006249024 + -4.5 x = 20.006249024 + -4.5 Combine like terms: 20.006249024 + -4.5 = 15.506249024 x = 15.506249024 Simplifying x = 15.506249024Subproblem 2
x + 4.5 = -20.006249024 Simplifying x + 4.5 = -20.006249024 Reorder the terms: 4.5 + x = -20.006249024 Solving 4.5 + x = -20.006249024 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 = -20.006249024 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -20.006249024 + -4.5 x = -20.006249024 + -4.5 Combine like terms: -20.006249024 + -4.5 = -24.506249024 x = -24.506249024 Simplifying x = -24.506249024Solution
The solution to the problem is based on the solutions from the subproblems. x = {15.506249024, -24.506249024}
