Simplifying x2 + -20x + 199 = 0 Reorder the terms: 199 + -20x + x2 = 0 Solving 199 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-199' to each side of the equation. 199 + -20x + -199 + x2 = 0 + -199 Reorder the terms: 199 + -199 + -20x + x2 = 0 + -199 Combine like terms: 199 + -199 = 0 0 + -20x + x2 = 0 + -199 -20x + x2 = 0 + -199 Combine like terms: 0 + -199 = -199 -20x + x2 = -199 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 = -199 + 100 Reorder the terms: 100 + -20x + x2 = -199 + 100 Combine like terms: -199 + 100 = -99 100 + -20x + x2 = -99 Factor a perfect square on the left side: (x + -10)(x + -10) = -99 Can't calculate square root of the right side. The solution to this equation could not be determined.
