Simplifying 4x2 + x + 1260 = 0 Reorder the terms: 1260 + x + 4x2 = 0 Solving 1260 + x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 315 + 0.25x + x2 = 0 Move the constant term to the right: Add '-315' to each side of the equation. 315 + 0.25x + -315 + x2 = 0 + -315 Reorder the terms: 315 + -315 + 0.25x + x2 = 0 + -315 Combine like terms: 315 + -315 = 0 0 + 0.25x + x2 = 0 + -315 0.25x + x2 = 0 + -315 Combine like terms: 0 + -315 = -315 0.25x + x2 = -315 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.25x + 0.25 + x2 = -315 + 0.25 Reorder the terms: 0.25 + 0.25x + x2 = -315 + 0.25 Combine like terms: -315 + 0.25 = -314.75 0.25 + 0.25x + x2 = -314.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -314.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
