Simplifying x2 + 24x + -1.6 = 0 Reorder the terms: -1.6 + 24x + x2 = 0 Solving -1.6 + 24x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + 24x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + 24x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + 24x + x2 = 0 + 1.6 24x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 24x + x2 = 1.6 The x term is 24x. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24x + 144 + x2 = 1.6 + 144 Reorder the terms: 144 + 24x + x2 = 1.6 + 144 Combine like terms: 1.6 + 144 = 145.6 144 + 24x + x2 = 145.6 Factor a perfect square on the left side: (x + 12)(x + 12) = 145.6 Calculate the square root of the right side: 12.066482503 Break this problem into two subproblems by setting (x + 12) equal to 12.066482503 and -12.066482503.Subproblem 1
x + 12 = 12.066482503 Simplifying x + 12 = 12.066482503 Reorder the terms: 12 + x = 12.066482503 Solving 12 + x = 12.066482503 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = 12.066482503 + -12 Combine like terms: 12 + -12 = 0 0 + x = 12.066482503 + -12 x = 12.066482503 + -12 Combine like terms: 12.066482503 + -12 = 0.066482503 x = 0.066482503 Simplifying x = 0.066482503Subproblem 2
x + 12 = -12.066482503 Simplifying x + 12 = -12.066482503 Reorder the terms: 12 + x = -12.066482503 Solving 12 + x = -12.066482503 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + x = -12.066482503 + -12 Combine like terms: 12 + -12 = 0 0 + x = -12.066482503 + -12 x = -12.066482503 + -12 Combine like terms: -12.066482503 + -12 = -24.066482503 x = -24.066482503 Simplifying x = -24.066482503Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.066482503, -24.066482503}
