Simplifying x2 + -3x + 9 = 0 Reorder the terms: 9 + -3x + x2 = 0 Solving 9 + -3x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -3x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -3x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -3x + x2 = 0 + -9 -3x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -3x + x2 = -9 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 = -9 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -9 + 2.25 Combine like terms: -9 + 2.25 = -6.75 2.25 + -3x + x2 = -6.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
