Simplifying x2 + 9x + 20.25 = -18 Reorder the terms: 20.25 + 9x + x2 = -18 Solving 20.25 + 9x + x2 = -18 Solving for variable 'x'. Reorder the terms: 20.25 + 18 + 9x + x2 = -18 + 18 Combine like terms: 20.25 + 18 = 38.25 38.25 + 9x + x2 = -18 + 18 Combine like terms: -18 + 18 = 0 38.25 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-38.25' to each side of the equation. 38.25 + 9x + -38.25 + x2 = 0 + -38.25 Reorder the terms: 38.25 + -38.25 + 9x + x2 = 0 + -38.25 Combine like terms: 38.25 + -38.25 = 0.00 0.00 + 9x + x2 = 0 + -38.25 9x + x2 = 0 + -38.25 Combine like terms: 0 + -38.25 = -38.25 9x + x2 = -38.25 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = -38.25 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -38.25 + 20.25 Combine like terms: -38.25 + 20.25 = -18 20.25 + 9x + x2 = -18 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = -18 Can't calculate square root of the right side. The solution to this equation could not be determined.
