Simplifying 4x2 + -24x + 81 = 0 Reorder the terms: 81 + -24x + 4x2 = 0 Solving 81 + -24x + 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 + -6x + x2 = 0 Move the constant term to the right: Add '-20.25' to each side of the equation. 20.25 + -6x + -20.25 + x2 = 0 + -20.25 Reorder the terms: 20.25 + -20.25 + -6x + x2 = 0 + -20.25 Combine like terms: 20.25 + -20.25 = 0.00 0.00 + -6x + x2 = 0 + -20.25 -6x + x2 = 0 + -20.25 Combine like terms: 0 + -20.25 = -20.25 -6x + x2 = -20.25 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -20.25 + 9 Reorder the terms: 9 + -6x + x2 = -20.25 + 9 Combine like terms: -20.25 + 9 = -11.25 9 + -6x + x2 = -11.25 Factor a perfect square on the left side: (x + -3)(x + -3) = -11.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
