Simplifying 4x2 + 12x + 81 = 0 Reorder the terms: 81 + 12x + 4x2 = 0 Solving 81 + 12x + 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'. 20.25 + 3x + x2 = 0 Move the constant term to the right: Add '-20.25' to each side of the equation. 20.25 + 3x + -20.25 + x2 = 0 + -20.25 Reorder the terms: 20.25 + -20.25 + 3x + x2 = 0 + -20.25 Combine like terms: 20.25 + -20.25 = 0.00 0.00 + 3x + x2 = 0 + -20.25 3x + x2 = 0 + -20.25 Combine like terms: 0 + -20.25 = -20.25 3x + x2 = -20.25 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = -20.25 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -20.25 + 2.25 Combine like terms: -20.25 + 2.25 = -18 2.25 + 3x + x2 = -18 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = -18 Can't calculate square root of the right side. The solution to this equation could not be determined.
