Simplifying (x2 + 6x + 9) + (3x + 2) = 0 Reorder the terms: (9 + 6x + x2) + (3x + 2) = 0 Remove parenthesis around (9 + 6x + x2) 9 + 6x + x2 + (3x + 2) = 0 Reorder the terms: 9 + 6x + x2 + (2 + 3x) = 0 Remove parenthesis around (2 + 3x) 9 + 6x + x2 + 2 + 3x = 0 Reorder the terms: 9 + 2 + 6x + 3x + x2 = 0 Combine like terms: 9 + 2 = 11 11 + 6x + 3x + x2 = 0 Combine like terms: 6x + 3x = 9x 11 + 9x + x2 = 0 Solving 11 + 9x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + 9x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + 9x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + 9x + x2 = 0 + -11 9x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 9x + x2 = -11 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = -11 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -11 + 20.25 Combine like terms: -11 + 20.25 = 9.25 20.25 + 9x + x2 = 9.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + 4.5) equal to 3.041381265 and -3.041381265.Subproblem 1
x + 4.5 = 3.041381265 Simplifying x + 4.5 = 3.041381265 Reorder the terms: 4.5 + x = 3.041381265 Solving 4.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 3.041381265 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 3.041381265 + -4.5 x = 3.041381265 + -4.5 Combine like terms: 3.041381265 + -4.5 = -1.458618735 x = -1.458618735 Simplifying x = -1.458618735Subproblem 2
x + 4.5 = -3.041381265 Simplifying x + 4.5 = -3.041381265 Reorder the terms: 4.5 + x = -3.041381265 Solving 4.5 + x = -3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -3.041381265 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -3.041381265 + -4.5 x = -3.041381265 + -4.5 Combine like terms: -3.041381265 + -4.5 = -7.541381265 x = -7.541381265 Simplifying x = -7.541381265Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.458618735, -7.541381265}
