Simplifying -7z + 9 = -7z2 Reorder the terms: 9 + -7z = -7z2 Solving 9 + -7z = -7z2 Solving for variable 'z'. Combine like terms: -7z2 + 7z2 = 0 9 + -7z + 7z2 = 0 Begin completing the square. Divide all terms by 7 the coefficient of the squared term: Divide each side by '7'. 1.285714286 + -1z + z2 = 0 Move the constant term to the right: Add '-1.285714286' to each side of the equation. 1.285714286 + -1z + -1.285714286 + z2 = 0 + -1.285714286 Reorder the terms: 1.285714286 + -1.285714286 + -1z + z2 = 0 + -1.285714286 Combine like terms: 1.285714286 + -1.285714286 = 0.000000000 0.000000000 + -1z + z2 = 0 + -1.285714286 -1z + z2 = 0 + -1.285714286 Combine like terms: 0 + -1.285714286 = -1.285714286 -1z + z2 = -1.285714286 The z term is -1z. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1z + 0.25 + z2 = -1.285714286 + 0.25 Reorder the terms: 0.25 + -1z + z2 = -1.285714286 + 0.25 Combine like terms: -1.285714286 + 0.25 = -1.035714286 0.25 + -1z + z2 = -1.035714286 Factor a perfect square on the left side: (z + -0.5)(z + -0.5) = -1.035714286 Can't calculate square root of the right side. The solution to this equation could not be determined.
