Simplifying x2 + 3x + -72 = 0 Reorder the terms: -72 + 3x + x2 = 0 Solving -72 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '72' to each side of the equation. -72 + 3x + 72 + x2 = 0 + 72 Reorder the terms: -72 + 72 + 3x + x2 = 0 + 72 Combine like terms: -72 + 72 = 0 0 + 3x + x2 = 0 + 72 3x + x2 = 0 + 72 Combine like terms: 0 + 72 = 72 3x + x2 = 72 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 72 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 72 + 2.25 Combine like terms: 72 + 2.25 = 74.25 2.25 + 3x + x2 = 74.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 74.25 Calculate the square root of the right side: 8.61684397 Break this problem into two subproblems by setting (x + 1.5) equal to 8.61684397 and -8.61684397.Subproblem 1
x + 1.5 = 8.61684397 Simplifying x + 1.5 = 8.61684397 Reorder the terms: 1.5 + x = 8.61684397 Solving 1.5 + x = 8.61684397 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 8.61684397 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 8.61684397 + -1.5 x = 8.61684397 + -1.5 Combine like terms: 8.61684397 + -1.5 = 7.11684397 x = 7.11684397 Simplifying x = 7.11684397Subproblem 2
x + 1.5 = -8.61684397 Simplifying x + 1.5 = -8.61684397 Reorder the terms: 1.5 + x = -8.61684397 Solving 1.5 + x = -8.61684397 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -8.61684397 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -8.61684397 + -1.5 x = -8.61684397 + -1.5 Combine like terms: -8.61684397 + -1.5 = -10.11684397 x = -10.11684397 Simplifying x = -10.11684397Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.11684397, -10.11684397}
