Simplifying s2 + -9s + 81 = 0 Reorder the terms: 81 + -9s + s2 = 0 Solving 81 + -9s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-81' to each side of the equation. 81 + -9s + -81 + s2 = 0 + -81 Reorder the terms: 81 + -81 + -9s + s2 = 0 + -81 Combine like terms: 81 + -81 = 0 0 + -9s + s2 = 0 + -81 -9s + s2 = 0 + -81 Combine like terms: 0 + -81 = -81 -9s + s2 = -81 The s term is -9s. 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. -9s + 20.25 + s2 = -81 + 20.25 Reorder the terms: 20.25 + -9s + s2 = -81 + 20.25 Combine like terms: -81 + 20.25 = -60.75 20.25 + -9s + s2 = -60.75 Factor a perfect square on the left side: (s + -4.5)(s + -4.5) = -60.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
