Simplifying 10x2 + -54x + 81 = 0 Reorder the terms: 81 + -54x + 10x2 = 0 Solving 81 + -54x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 8.1 + -5.4x + x2 = 0 Move the constant term to the right: Add '-8.1' to each side of the equation. 8.1 + -5.4x + -8.1 + x2 = 0 + -8.1 Reorder the terms: 8.1 + -8.1 + -5.4x + x2 = 0 + -8.1 Combine like terms: 8.1 + -8.1 = 0.0 0.0 + -5.4x + x2 = 0 + -8.1 -5.4x + x2 = 0 + -8.1 Combine like terms: 0 + -8.1 = -8.1 -5.4x + x2 = -8.1 The x term is -5.4x. Take half its coefficient (-2.7). Square it (7.29) and add it to both sides. Add '7.29' to each side of the equation. -5.4x + 7.29 + x2 = -8.1 + 7.29 Reorder the terms: 7.29 + -5.4x + x2 = -8.1 + 7.29 Combine like terms: -8.1 + 7.29 = -0.81 7.29 + -5.4x + x2 = -0.81 Factor a perfect square on the left side: (x + -2.7)(x + -2.7) = -0.81 Can't calculate square root of the right side. The solution to this equation could not be determined.
