Simplifying x2 + 18x + 63 = 0 Reorder the terms: 63 + 18x + x2 = 0 Solving 63 + 18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-63' to each side of the equation. 63 + 18x + -63 + x2 = 0 + -63 Reorder the terms: 63 + -63 + 18x + x2 = 0 + -63 Combine like terms: 63 + -63 = 0 0 + 18x + x2 = 0 + -63 18x + x2 = 0 + -63 Combine like terms: 0 + -63 = -63 18x + x2 = -63 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 = -63 + 81 Reorder the terms: 81 + 18x + x2 = -63 + 81 Combine like terms: -63 + 81 = 18 81 + 18x + x2 = 18 Factor a perfect square on the left side: (x + 9)(x + 9) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (x + 9) equal to 4.242640687 and -4.242640687.Subproblem 1
x + 9 = 4.242640687 Simplifying x + 9 = 4.242640687 Reorder the terms: 9 + x = 4.242640687 Solving 9 + x = 4.242640687 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 = 4.242640687 + -9 Combine like terms: 9 + -9 = 0 0 + x = 4.242640687 + -9 x = 4.242640687 + -9 Combine like terms: 4.242640687 + -9 = -4.757359313 x = -4.757359313 Simplifying x = -4.757359313Subproblem 2
x + 9 = -4.242640687 Simplifying x + 9 = -4.242640687 Reorder the terms: 9 + x = -4.242640687 Solving 9 + x = -4.242640687 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 = -4.242640687 + -9 Combine like terms: 9 + -9 = 0 0 + x = -4.242640687 + -9 x = -4.242640687 + -9 Combine like terms: -4.242640687 + -9 = -13.242640687 x = -13.242640687 Simplifying x = -13.242640687Solution
The solution to the problem is based on the solutions from the subproblems. x = {-4.757359313, -13.242640687}
