Simplifying x2 + -20x + 119 = 0 Reorder the terms: 119 + -20x + x2 = 0 Solving 119 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-119' to each side of the equation. 119 + -20x + -119 + x2 = 0 + -119 Reorder the terms: 119 + -119 + -20x + x2 = 0 + -119 Combine like terms: 119 + -119 = 0 0 + -20x + x2 = 0 + -119 -20x + x2 = 0 + -119 Combine like terms: 0 + -119 = -119 -20x + x2 = -119 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -119 + 100 Reorder the terms: 100 + -20x + x2 = -119 + 100 Combine like terms: -119 + 100 = -19 100 + -20x + x2 = -19 Factor a perfect square on the left side: (x + -10)(x + -10) = -19 Can't calculate square root of the right side. The solution to this equation could not be determined.
