Simplifying x2 + -6x + 9 = -25 Reorder the terms: 9 + -6x + x2 = -25 Solving 9 + -6x + x2 = -25 Solving for variable 'x'. Reorder the terms: 9 + 25 + -6x + x2 = -25 + 25 Combine like terms: 9 + 25 = 34 34 + -6x + x2 = -25 + 25 Combine like terms: -25 + 25 = 0 34 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-34' to each side of the equation. 34 + -6x + -34 + x2 = 0 + -34 Reorder the terms: 34 + -34 + -6x + x2 = 0 + -34 Combine like terms: 34 + -34 = 0 0 + -6x + x2 = 0 + -34 -6x + x2 = 0 + -34 Combine like terms: 0 + -34 = -34 -6x + x2 = -34 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 = -34 + 9 Reorder the terms: 9 + -6x + x2 = -34 + 9 Combine like terms: -34 + 9 = -25 9 + -6x + x2 = -25 Factor a perfect square on the left side: (x + -3)(x + -3) = -25 Can't calculate square root of the right side. The solution to this equation could not be determined.
