Simplifying s2 + 10s + 27 = 0 Reorder the terms: 27 + 10s + s2 = 0 Solving 27 + 10s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-27' to each side of the equation. 27 + 10s + -27 + s2 = 0 + -27 Reorder the terms: 27 + -27 + 10s + s2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + 10s + s2 = 0 + -27 10s + s2 = 0 + -27 Combine like terms: 0 + -27 = -27 10s + s2 = -27 The s term is 10s. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10s + 25 + s2 = -27 + 25 Reorder the terms: 25 + 10s + s2 = -27 + 25 Combine like terms: -27 + 25 = -2 25 + 10s + s2 = -2 Factor a perfect square on the left side: (s + 5)(s + 5) = -2 Can't calculate square root of the right side. The solution to this equation could not be determined.
