Simplifying x2 + -5x + -4x = 158 Reorder the terms: -5x + -4x + x2 = 158 Combine like terms: -5x + -4x = -9x -9x + x2 = 158 Solving -9x + x2 = 158 Solving for variable 'x'. Reorder the terms: -158 + -9x + x2 = 158 + -158 Combine like terms: 158 + -158 = 0 -158 + -9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '158' to each side of the equation. -158 + -9x + 158 + x2 = 0 + 158 Reorder the terms: -158 + 158 + -9x + x2 = 0 + 158 Combine like terms: -158 + 158 = 0 0 + -9x + x2 = 0 + 158 -9x + x2 = 0 + 158 Combine like terms: 0 + 158 = 158 -9x + x2 = 158 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 = 158 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 158 + 20.25 Combine like terms: 158 + 20.25 = 178.25 20.25 + -9x + x2 = 178.25 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 178.25 Calculate the square root of the right side: 13.351029923 Break this problem into two subproblems by setting (x + -4.5) equal to 13.351029923 and -13.351029923.Subproblem 1
x + -4.5 = 13.351029923 Simplifying x + -4.5 = 13.351029923 Reorder the terms: -4.5 + x = 13.351029923 Solving -4.5 + x = 13.351029923 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 = 13.351029923 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 13.351029923 + 4.5 x = 13.351029923 + 4.5 Combine like terms: 13.351029923 + 4.5 = 17.851029923 x = 17.851029923 Simplifying x = 17.851029923Subproblem 2
x + -4.5 = -13.351029923 Simplifying x + -4.5 = -13.351029923 Reorder the terms: -4.5 + x = -13.351029923 Solving -4.5 + x = -13.351029923 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 = -13.351029923 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -13.351029923 + 4.5 x = -13.351029923 + 4.5 Combine like terms: -13.351029923 + 4.5 = -8.851029923 x = -8.851029923 Simplifying x = -8.851029923Solution
The solution to the problem is based on the solutions from the subproblems. x = {17.851029923, -8.851029923}
