Simplifying 2x2 + -24x + 169 = 0 Reorder the terms: 169 + -24x + 2x2 = 0 Solving 169 + -24x + 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'. 84.5 + -12x + x2 = 0 Move the constant term to the right: Add '-84.5' to each side of the equation. 84.5 + -12x + -84.5 + x2 = 0 + -84.5 Reorder the terms: 84.5 + -84.5 + -12x + x2 = 0 + -84.5 Combine like terms: 84.5 + -84.5 = 0.0 0.0 + -12x + x2 = 0 + -84.5 -12x + x2 = 0 + -84.5 Combine like terms: 0 + -84.5 = -84.5 -12x + x2 = -84.5 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = -84.5 + 36 Reorder the terms: 36 + -12x + x2 = -84.5 + 36 Combine like terms: -84.5 + 36 = -48.5 36 + -12x + x2 = -48.5 Factor a perfect square on the left side: (x + -6)(x + -6) = -48.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
