Simplifying z2 + -14z + 49 = -144 Reorder the terms: 49 + -14z + z2 = -144 Solving 49 + -14z + z2 = -144 Solving for variable 'z'. Reorder the terms: 49 + 144 + -14z + z2 = -144 + 144 Combine like terms: 49 + 144 = 193 193 + -14z + z2 = -144 + 144 Combine like terms: -144 + 144 = 0 193 + -14z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '-193' to each side of the equation. 193 + -14z + -193 + z2 = 0 + -193 Reorder the terms: 193 + -193 + -14z + z2 = 0 + -193 Combine like terms: 193 + -193 = 0 0 + -14z + z2 = 0 + -193 -14z + z2 = 0 + -193 Combine like terms: 0 + -193 = -193 -14z + z2 = -193 The z term is -14z. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14z + 49 + z2 = -193 + 49 Reorder the terms: 49 + -14z + z2 = -193 + 49 Combine like terms: -193 + 49 = -144 49 + -14z + z2 = -144 Factor a perfect square on the left side: (z + -7)(z + -7) = -144 Can't calculate square root of the right side. The solution to this equation could not be determined.
