Simplifying x2 + 29x + -100 = 0 Reorder the terms: -100 + 29x + x2 = 0 Solving -100 + 29x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '100' to each side of the equation. -100 + 29x + 100 + x2 = 0 + 100 Reorder the terms: -100 + 100 + 29x + x2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + 29x + x2 = 0 + 100 29x + x2 = 0 + 100 Combine like terms: 0 + 100 = 100 29x + x2 = 100 The x term is 29x. Take half its coefficient (14.5). Square it (210.25) and add it to both sides. Add '210.25' to each side of the equation. 29x + 210.25 + x2 = 100 + 210.25 Reorder the terms: 210.25 + 29x + x2 = 100 + 210.25 Combine like terms: 100 + 210.25 = 310.25 210.25 + 29x + x2 = 310.25 Factor a perfect square on the left side: (x + 14.5)(x + 14.5) = 310.25 Calculate the square root of the right side: 17.613914954 Break this problem into two subproblems by setting (x + 14.5) equal to 17.613914954 and -17.613914954.Subproblem 1
x + 14.5 = 17.613914954 Simplifying x + 14.5 = 17.613914954 Reorder the terms: 14.5 + x = 17.613914954 Solving 14.5 + x = 17.613914954 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = 17.613914954 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = 17.613914954 + -14.5 x = 17.613914954 + -14.5 Combine like terms: 17.613914954 + -14.5 = 3.113914954 x = 3.113914954 Simplifying x = 3.113914954Subproblem 2
x + 14.5 = -17.613914954 Simplifying x + 14.5 = -17.613914954 Reorder the terms: 14.5 + x = -17.613914954 Solving 14.5 + x = -17.613914954 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = -17.613914954 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = -17.613914954 + -14.5 x = -17.613914954 + -14.5 Combine like terms: -17.613914954 + -14.5 = -32.113914954 x = -32.113914954 Simplifying x = -32.113914954Solution
