Simplifying 2x2 + -10x + 169 = 0 Reorder the terms: 169 + -10x + 2x2 = 0 Solving 169 + -10x + 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 + -5x + x2 = 0 Move the constant term to the right: Add '-84.5' to each side of the equation. 84.5 + -5x + -84.5 + x2 = 0 + -84.5 Reorder the terms: 84.5 + -84.5 + -5x + x2 = 0 + -84.5 Combine like terms: 84.5 + -84.5 = 0.0 0.0 + -5x + x2 = 0 + -84.5 -5x + x2 = 0 + -84.5 Combine like terms: 0 + -84.5 = -84.5 -5x + x2 = -84.5 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -84.5 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -84.5 + 6.25 Combine like terms: -84.5 + 6.25 = -78.25 6.25 + -5x + x2 = -78.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -78.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
