Simplifying 2x2 + -21x + 216 = 0 Reorder the terms: 216 + -21x + 2x2 = 0 Solving 216 + -21x + 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'. 108 + -10.5x + x2 = 0 Move the constant term to the right: Add '-108' to each side of the equation. 108 + -10.5x + -108 + x2 = 0 + -108 Reorder the terms: 108 + -108 + -10.5x + x2 = 0 + -108 Combine like terms: 108 + -108 = 0 0 + -10.5x + x2 = 0 + -108 -10.5x + x2 = 0 + -108 Combine like terms: 0 + -108 = -108 -10.5x + x2 = -108 The x term is -10.5x. Take half its coefficient (-5.25). Square it (27.5625) and add it to both sides. Add '27.5625' to each side of the equation. -10.5x + 27.5625 + x2 = -108 + 27.5625 Reorder the terms: 27.5625 + -10.5x + x2 = -108 + 27.5625 Combine like terms: -108 + 27.5625 = -80.4375 27.5625 + -10.5x + x2 = -80.4375 Factor a perfect square on the left side: (x + -5.25)(x + -5.25) = -80.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
