Simplifying x2 + 19x + -16 = 0 Reorder the terms: -16 + 19x + x2 = 0 Solving -16 + 19x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '16' to each side of the equation. -16 + 19x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + 19x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 19x + x2 = 0 + 16 19x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 19x + x2 = 16 The x term is 19x. Take half its coefficient (9.5). Square it (90.25) and add it to both sides. Add '90.25' to each side of the equation. 19x + 90.25 + x2 = 16 + 90.25 Reorder the terms: 90.25 + 19x + x2 = 16 + 90.25 Combine like terms: 16 + 90.25 = 106.25 90.25 + 19x + x2 = 106.25 Factor a perfect square on the left side: (x + 9.5)(x + 9.5) = 106.25 Calculate the square root of the right side: 10.307764064 Break this problem into two subproblems by setting (x + 9.5) equal to 10.307764064 and -10.307764064.Subproblem 1
x + 9.5 = 10.307764064 Simplifying x + 9.5 = 10.307764064 Reorder the terms: 9.5 + x = 10.307764064 Solving 9.5 + x = 10.307764064 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = 10.307764064 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = 10.307764064 + -9.5 x = 10.307764064 + -9.5 Combine like terms: 10.307764064 + -9.5 = 0.807764064 x = 0.807764064 Simplifying x = 0.807764064Subproblem 2
x + 9.5 = -10.307764064 Simplifying x + 9.5 = -10.307764064 Reorder the terms: 9.5 + x = -10.307764064 Solving 9.5 + x = -10.307764064 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = -10.307764064 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = -10.307764064 + -9.5 x = -10.307764064 + -9.5 Combine like terms: -10.307764064 + -9.5 = -19.807764064 x = -19.807764064 Simplifying x = -19.807764064Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.807764064, -19.807764064}
