Simplifying x2 + -4x + 9 = 0 Reorder the terms: 9 + -4x + x2 = 0 Solving 9 + -4x + 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 + -4x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -4x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -4x + x2 = 0 + -9 -4x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -4x + x2 = -9 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -9 + 4 Reorder the terms: 4 + -4x + x2 = -9 + 4 Combine like terms: -9 + 4 = -5 4 + -4x + x2 = -5 Factor a perfect square on the left side: (x + -2)(x + -2) = -5 Can't calculate square root of the right side. The solution to this equation could not be determined.
