Simplifying 2x2 + 14x + 39 = 0 Reorder the terms: 39 + 14x + 2x2 = 0 Solving 39 + 14x + 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'. 19.5 + 7x + x2 = 0 Move the constant term to the right: Add '-19.5' to each side of the equation. 19.5 + 7x + -19.5 + x2 = 0 + -19.5 Reorder the terms: 19.5 + -19.5 + 7x + x2 = 0 + -19.5 Combine like terms: 19.5 + -19.5 = 0.0 0.0 + 7x + x2 = 0 + -19.5 7x + x2 = 0 + -19.5 Combine like terms: 0 + -19.5 = -19.5 7x + x2 = -19.5 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = -19.5 + 12.25 Reorder the terms: 12.25 + 7x + x2 = -19.5 + 12.25 Combine like terms: -19.5 + 12.25 = -7.25 12.25 + 7x + x2 = -7.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = -7.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
