Simplifying -2x2 + x + -28 = 0 Reorder the terms: -28 + x + -2x2 = 0 Solving -28 + x + -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'. 14 + -0.5x + x2 = 0 Move the constant term to the right: Add '-14' to each side of the equation. 14 + -0.5x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + -0.5x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -0.5x + x2 = 0 + -14 -0.5x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 -0.5x + x2 = -14 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. -0.5x + 0.25 + x2 = -14 + 0.25 Reorder the terms: 0.25 + -0.5x + x2 = -14 + 0.25 Combine like terms: -14 + 0.25 = -13.75 0.25 + -0.5x + x2 = -13.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -13.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
