Simplifying x2 + -19x + 361 = 0 Reorder the terms: 361 + -19x + x2 = 0 Solving 361 + -19x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-361' to each side of the equation. 361 + -19x + -361 + x2 = 0 + -361 Reorder the terms: 361 + -361 + -19x + x2 = 0 + -361 Combine like terms: 361 + -361 = 0 0 + -19x + x2 = 0 + -361 -19x + x2 = 0 + -361 Combine like terms: 0 + -361 = -361 -19x + x2 = -361 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 = -361 + 90.25 Reorder the terms: 90.25 + -19x + x2 = -361 + 90.25 Combine like terms: -361 + 90.25 = -270.75 90.25 + -19x + x2 = -270.75 Factor a perfect square on the left side: (x + -9.5)(x + -9.5) = -270.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
