Simplifying 2x2 + -22x + 63 = 0 Reorder the terms: 63 + -22x + 2x2 = 0 Solving 63 + -22x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 31.5 + -11x + x2 = 0 Move the constant term to the right: Add '-31.5' to each side of the equation. 31.5 + -11x + -31.5 + x2 = 0 + -31.5 Reorder the terms: 31.5 + -31.5 + -11x + x2 = 0 + -31.5 Combine like terms: 31.5 + -31.5 = 0.0 0.0 + -11x + x2 = 0 + -31.5 -11x + x2 = 0 + -31.5 Combine like terms: 0 + -31.5 = -31.5 -11x + x2 = -31.5 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = -31.5 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -31.5 + 30.25 Combine like terms: -31.5 + 30.25 = -1.25 30.25 + -11x + x2 = -1.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = -1.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
