Simplifying 5x2 + -9x + 256 = 0 Reorder the terms: 256 + -9x + 5x2 = 0 Solving 256 + -9x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 51.2 + -1.8x + x2 = 0 Move the constant term to the right: Add '-51.2' to each side of the equation. 51.2 + -1.8x + -51.2 + x2 = 0 + -51.2 Reorder the terms: 51.2 + -51.2 + -1.8x + x2 = 0 + -51.2 Combine like terms: 51.2 + -51.2 = 0.0 0.0 + -1.8x + x2 = 0 + -51.2 -1.8x + x2 = 0 + -51.2 Combine like terms: 0 + -51.2 = -51.2 -1.8x + x2 = -51.2 The x term is -1.8x. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8x + 0.81 + x2 = -51.2 + 0.81 Reorder the terms: 0.81 + -1.8x + x2 = -51.2 + 0.81 Combine like terms: -51.2 + 0.81 = -50.39 0.81 + -1.8x + x2 = -50.39 Factor a perfect square on the left side: (x + -0.9)(x + -0.9) = -50.39 Can't calculate square root of the right side. The solution to this equation could not be determined.
