Simplifying x2 + 19x = 1 Reorder the terms: 19x + x2 = 1 Solving 19x + x2 = 1 Solving for variable 'x'. Reorder the terms: -1 + 19x + x2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + 19x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + 19x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 19x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 19x + x2 = 0 + 1 19x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 19x + x2 = 1 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 = 1 + 90.25 Reorder the terms: 90.25 + 19x + x2 = 1 + 90.25 Combine like terms: 1 + 90.25 = 91.25 90.25 + 19x + x2 = 91.25 Factor a perfect square on the left side: (x + 9.5)(x + 9.5) = 91.25 Calculate the square root of the right side: 9.552486587 Break this problem into two subproblems by setting (x + 9.5) equal to 9.552486587 and -9.552486587.Subproblem 1
x + 9.5 = 9.552486587 Simplifying x + 9.5 = 9.552486587 Reorder the terms: 9.5 + x = 9.552486587 Solving 9.5 + x = 9.552486587 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 = 9.552486587 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = 9.552486587 + -9.5 x = 9.552486587 + -9.5 Combine like terms: 9.552486587 + -9.5 = 0.052486587 x = 0.052486587 Simplifying x = 0.052486587Subproblem 2
x + 9.5 = -9.552486587 Simplifying x + 9.5 = -9.552486587 Reorder the terms: 9.5 + x = -9.552486587 Solving 9.5 + x = -9.552486587 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 = -9.552486587 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = -9.552486587 + -9.5 x = -9.552486587 + -9.5 Combine like terms: -9.552486587 + -9.5 = -19.052486587 x = -19.052486587 Simplifying x = -19.052486587Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.052486587, -19.052486587}
