Simplifying x2 + -6x + 9 = -400 Reorder the terms: 9 + -6x + x2 = -400 Solving 9 + -6x + x2 = -400 Solving for variable 'x'. Reorder the terms: 9 + 400 + -6x + x2 = -400 + 400 Combine like terms: 9 + 400 = 409 409 + -6x + x2 = -400 + 400 Combine like terms: -400 + 400 = 0 409 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-409' to each side of the equation. 409 + -6x + -409 + x2 = 0 + -409 Reorder the terms: 409 + -409 + -6x + x2 = 0 + -409 Combine like terms: 409 + -409 = 0 0 + -6x + x2 = 0 + -409 -6x + x2 = 0 + -409 Combine like terms: 0 + -409 = -409 -6x + x2 = -409 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 = -409 + 9 Reorder the terms: 9 + -6x + x2 = -409 + 9 Combine like terms: -409 + 9 = -400 9 + -6x + x2 = -400 Factor a perfect square on the left side: (x + -3)(x + -3) = -400 Can't calculate square root of the right side. The solution to this equation could not be determined.
