Simplifying x2 + -19x + 102 = 0 Reorder the terms: 102 + -19x + x2 = 0 Solving 102 + -19x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-102' to each side of the equation. 102 + -19x + -102 + x2 = 0 + -102 Reorder the terms: 102 + -102 + -19x + x2 = 0 + -102 Combine like terms: 102 + -102 = 0 0 + -19x + x2 = 0 + -102 -19x + x2 = 0 + -102 Combine like terms: 0 + -102 = -102 -19x + x2 = -102 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 = -102 + 90.25 Reorder the terms: 90.25 + -19x + x2 = -102 + 90.25 Combine like terms: -102 + 90.25 = -11.75 90.25 + -19x + x2 = -11.75 Factor a perfect square on the left side: (x + -9.5)(x + -9.5) = -11.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
