Simplifying x2 + 3x + -800 = 0 Reorder the terms: -800 + 3x + x2 = 0 Solving -800 + 3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '800' to each side of the equation. -800 + 3x + 800 + x2 = 0 + 800 Reorder the terms: -800 + 800 + 3x + x2 = 0 + 800 Combine like terms: -800 + 800 = 0 0 + 3x + x2 = 0 + 800 3x + x2 = 0 + 800 Combine like terms: 0 + 800 = 800 3x + x2 = 800 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 = 800 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 800 + 2.25 Combine like terms: 800 + 2.25 = 802.25 2.25 + 3x + x2 = 802.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 802.25 Calculate the square root of the right side: 28.324018077 Break this problem into two subproblems by setting (x + 1.5) equal to 28.324018077 and -28.324018077.Subproblem 1
x + 1.5 = 28.324018077 Simplifying x + 1.5 = 28.324018077 Reorder the terms: 1.5 + x = 28.324018077 Solving 1.5 + x = 28.324018077 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 = 28.324018077 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 28.324018077 + -1.5 x = 28.324018077 + -1.5 Combine like terms: 28.324018077 + -1.5 = 26.824018077 x = 26.824018077 Simplifying x = 26.824018077Subproblem 2
x + 1.5 = -28.324018077 Simplifying x + 1.5 = -28.324018077 Reorder the terms: 1.5 + x = -28.324018077 Solving 1.5 + x = -28.324018077 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 = -28.324018077 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -28.324018077 + -1.5 x = -28.324018077 + -1.5 Combine like terms: -28.324018077 + -1.5 = -29.824018077 x = -29.824018077 Simplifying x = -29.824018077Solution
The solution to the problem is based on the solutions from the subproblems. x = {26.824018077, -29.824018077}
