Simplifying x2 + 20x + -320 = 0 Reorder the terms: -320 + 20x + x2 = 0 Solving -320 + 20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '320' to each side of the equation. -320 + 20x + 320 + x2 = 0 + 320 Reorder the terms: -320 + 320 + 20x + x2 = 0 + 320 Combine like terms: -320 + 320 = 0 0 + 20x + x2 = 0 + 320 20x + x2 = 0 + 320 Combine like terms: 0 + 320 = 320 20x + x2 = 320 The x term is 20x. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20x + 100 + x2 = 320 + 100 Reorder the terms: 100 + 20x + x2 = 320 + 100 Combine like terms: 320 + 100 = 420 100 + 20x + x2 = 420 Factor a perfect square on the left side: (x + 10)(x + 10) = 420 Calculate the square root of the right side: 20.493901532 Break this problem into two subproblems by setting (x + 10) equal to 20.493901532 and -20.493901532.Subproblem 1
x + 10 = 20.493901532 Simplifying x + 10 = 20.493901532 Reorder the terms: 10 + x = 20.493901532 Solving 10 + x = 20.493901532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 20.493901532 + -10 Combine like terms: 10 + -10 = 0 0 + x = 20.493901532 + -10 x = 20.493901532 + -10 Combine like terms: 20.493901532 + -10 = 10.493901532 x = 10.493901532 Simplifying x = 10.493901532Subproblem 2
x + 10 = -20.493901532 Simplifying x + 10 = -20.493901532 Reorder the terms: 10 + x = -20.493901532 Solving 10 + x = -20.493901532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = -20.493901532 + -10 Combine like terms: 10 + -10 = 0 0 + x = -20.493901532 + -10 x = -20.493901532 + -10 Combine like terms: -20.493901532 + -10 = -30.493901532 x = -30.493901532 Simplifying x = -30.493901532Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.493901532, -30.493901532}
