Simplifying -2x2 + x = 5 Reorder the terms: x + -2x2 = 5 Solving x + -2x2 = 5 Solving for variable 'x'. Reorder the terms: -5 + x + -2x2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 2.5 + -0.5x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -0.5x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -0.5x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -0.5x + x2 = 0 + -2.5 -0.5x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -0.5x + x2 = -2.5 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 = -2.5 + 0.25 Reorder the terms: 0.25 + -0.5x + x2 = -2.5 + 0.25 Combine like terms: -2.5 + 0.25 = -2.25 0.25 + -0.5x + x2 = -2.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -2.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
