Simplifying x2 + 38x + 59 = 0 Reorder the terms: 59 + 38x + x2 = 0 Solving 59 + 38x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-59' to each side of the equation. 59 + 38x + -59 + x2 = 0 + -59 Reorder the terms: 59 + -59 + 38x + x2 = 0 + -59 Combine like terms: 59 + -59 = 0 0 + 38x + x2 = 0 + -59 38x + x2 = 0 + -59 Combine like terms: 0 + -59 = -59 38x + x2 = -59 The x term is 38x. Take half its coefficient (19). Square it (361) and add it to both sides. Add '361' to each side of the equation. 38x + 361 + x2 = -59 + 361 Reorder the terms: 361 + 38x + x2 = -59 + 361 Combine like terms: -59 + 361 = 302 361 + 38x + x2 = 302 Factor a perfect square on the left side: (x + 19)(x + 19) = 302 Calculate the square root of the right side: 17.378147197 Break this problem into two subproblems by setting (x + 19) equal to 17.378147197 and -17.378147197.Subproblem 1
x + 19 = 17.378147197 Simplifying x + 19 = 17.378147197 Reorder the terms: 19 + x = 17.378147197 Solving 19 + x = 17.378147197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + -19 + x = 17.378147197 + -19 Combine like terms: 19 + -19 = 0 0 + x = 17.378147197 + -19 x = 17.378147197 + -19 Combine like terms: 17.378147197 + -19 = -1.621852803 x = -1.621852803 Simplifying x = -1.621852803Subproblem 2
x + 19 = -17.378147197 Simplifying x + 19 = -17.378147197 Reorder the terms: 19 + x = -17.378147197 Solving 19 + x = -17.378147197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + -19 + x = -17.378147197 + -19 Combine like terms: 19 + -19 = 0 0 + x = -17.378147197 + -19 x = -17.378147197 + -19 Combine like terms: -17.378147197 + -19 = -36.378147197 x = -36.378147197 Simplifying x = -36.378147197Solution
