Simplifying s2 + 11s + 49 = 0 Reorder the terms: 49 + 11s + s2 = 0 Solving 49 + 11s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-49' to each side of the equation. 49 + 11s + -49 + s2 = 0 + -49 Reorder the terms: 49 + -49 + 11s + s2 = 0 + -49 Combine like terms: 49 + -49 = 0 0 + 11s + s2 = 0 + -49 11s + s2 = 0 + -49 Combine like terms: 0 + -49 = -49 11s + s2 = -49 The s term is 11s. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11s + 30.25 + s2 = -49 + 30.25 Reorder the terms: 30.25 + 11s + s2 = -49 + 30.25 Combine like terms: -49 + 30.25 = -18.75 30.25 + 11s + s2 = -18.75 Factor a perfect square on the left side: (s + 5.5)(s + 5.5) = -18.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
