Simplifying x2 + 18x + 53 = 0 Reorder the terms: 53 + 18x + x2 = 0 Solving 53 + 18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-53' to each side of the equation. 53 + 18x + -53 + x2 = 0 + -53 Reorder the terms: 53 + -53 + 18x + x2 = 0 + -53 Combine like terms: 53 + -53 = 0 0 + 18x + x2 = 0 + -53 18x + x2 = 0 + -53 Combine like terms: 0 + -53 = -53 18x + x2 = -53 The x term is 18x. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18x + 81 + x2 = -53 + 81 Reorder the terms: 81 + 18x + x2 = -53 + 81 Combine like terms: -53 + 81 = 28 81 + 18x + x2 = 28 Factor a perfect square on the left side: (x + 9)(x + 9) = 28 Calculate the square root of the right side: 5.291502622 Break this problem into two subproblems by setting (x + 9) equal to 5.291502622 and -5.291502622.Subproblem 1
x + 9 = 5.291502622 Simplifying x + 9 = 5.291502622 Reorder the terms: 9 + x = 5.291502622 Solving 9 + x = 5.291502622 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = 5.291502622 + -9 Combine like terms: 9 + -9 = 0 0 + x = 5.291502622 + -9 x = 5.291502622 + -9 Combine like terms: 5.291502622 + -9 = -3.708497378 x = -3.708497378 Simplifying x = -3.708497378Subproblem 2
x + 9 = -5.291502622 Simplifying x + 9 = -5.291502622 Reorder the terms: 9 + x = -5.291502622 Solving 9 + x = -5.291502622 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = -5.291502622 + -9 Combine like terms: 9 + -9 = 0 0 + x = -5.291502622 + -9 x = -5.291502622 + -9 Combine like terms: -5.291502622 + -9 = -14.291502622 x = -14.291502622 Simplifying x = -14.291502622Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.708497378, -14.291502622}
