Simplifying x2 + -4x + 9 = -9 Reorder the terms: 9 + -4x + x2 = -9 Solving 9 + -4x + x2 = -9 Solving for variable 'x'. Reorder the terms: 9 + 9 + -4x + x2 = -9 + 9 Combine like terms: 9 + 9 = 18 18 + -4x + x2 = -9 + 9 Combine like terms: -9 + 9 = 0 18 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + -4x + -18 + x2 = 0 + -18 Reorder the terms: 18 + -18 + -4x + x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -4x + x2 = 0 + -18 -4x + x2 = 0 + -18 Combine like terms: 0 + -18 = -18 -4x + x2 = -18 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 = -18 + 4 Reorder the terms: 4 + -4x + x2 = -18 + 4 Combine like terms: -18 + 4 = -14 4 + -4x + x2 = -14 Factor a perfect square on the left side: (x + -2)(x + -2) = -14 Can't calculate square root of the right side. The solution to this equation could not be determined.
