Simplifying z2 + 4z + 9 = 0 Reorder the terms: 9 + 4z + z2 = 0 Solving 9 + 4z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + 4z + -9 + z2 = 0 + -9 Reorder the terms: 9 + -9 + 4z + z2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 4z + z2 = 0 + -9 4z + z2 = 0 + -9 Combine like terms: 0 + -9 = -9 4z + z2 = -9 The z term is 4z. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4z + 4 + z2 = -9 + 4 Reorder the terms: 4 + 4z + z2 = -9 + 4 Combine like terms: -9 + 4 = -5 4 + 4z + z2 = -5 Factor a perfect square on the left side: (z + 2)(z + 2) = -5 Can't calculate square root of the right side. The solution to this equation could not be determined.
