Simplifying x * x = -9x + -5 Multiply x * x x2 = -9x + -5 Reorder the terms: x2 = -5 + -9x Solving x2 = -5 + -9x Solving for variable 'x'. Reorder the terms: 5 + 9x + x2 = -5 + -9x + 5 + 9x Reorder the terms: 5 + 9x + x2 = -5 + 5 + -9x + 9x Combine like terms: -5 + 5 = 0 5 + 9x + x2 = 0 + -9x + 9x 5 + 9x + x2 = -9x + 9x Combine like terms: -9x + 9x = 0 5 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-5' to each side of the equation. 5 + 9x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + 9x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 9x + x2 = 0 + -5 9x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 9x + x2 = -5 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 = -5 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -5 + 20.25 Combine like terms: -5 + 20.25 = 15.25 20.25 + 9x + x2 = 15.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 15.25 Calculate the square root of the right side: 3.905124838 Break this problem into two subproblems by setting (x + 4.5) equal to 3.905124838 and -3.905124838.Subproblem 1
x + 4.5 = 3.905124838 Simplifying x + 4.5 = 3.905124838 Reorder the terms: 4.5 + x = 3.905124838 Solving 4.5 + x = 3.905124838 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 = 3.905124838 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 3.905124838 + -4.5 x = 3.905124838 + -4.5 Combine like terms: 3.905124838 + -4.5 = -0.594875162 x = -0.594875162 Simplifying x = -0.594875162Subproblem 2
x + 4.5 = -3.905124838 Simplifying x + 4.5 = -3.905124838 Reorder the terms: 4.5 + x = -3.905124838 Solving 4.5 + x = -3.905124838 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 = -3.905124838 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -3.905124838 + -4.5 x = -3.905124838 + -4.5 Combine like terms: -3.905124838 + -4.5 = -8.405124838 x = -8.405124838 Simplifying x = -8.405124838Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.594875162, -8.405124838}
