Simplifying 2x2 + x + 7 = 0 Reorder the terms: 7 + x + 2x2 = 0 Solving 7 + 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'. 3.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '-3.5' to each side of the equation. 3.5 + 0.5x + -3.5 + x2 = 0 + -3.5 Reorder the terms: 3.5 + -3.5 + 0.5x + x2 = 0 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + 0.5x + x2 = 0 + -3.5 0.5x + x2 = 0 + -3.5 Combine like terms: 0 + -3.5 = -3.5 0.5x + x2 = -3.5 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 = -3.5 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = -3.5 + 0.25 Combine like terms: -3.5 + 0.25 = -3.25 0.25 + 0.5x + x2 = -3.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -3.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
