Simplifying s2 + 4s + 21 = 0 Reorder the terms: 21 + 4s + s2 = 0 Solving 21 + 4s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-21' to each side of the equation. 21 + 4s + -21 + s2 = 0 + -21 Reorder the terms: 21 + -21 + 4s + s2 = 0 + -21 Combine like terms: 21 + -21 = 0 0 + 4s + s2 = 0 + -21 4s + s2 = 0 + -21 Combine like terms: 0 + -21 = -21 4s + s2 = -21 The s term is 4s. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4s + 4 + s2 = -21 + 4 Reorder the terms: 4 + 4s + s2 = -21 + 4 Combine like terms: -21 + 4 = -17 4 + 4s + s2 = -17 Factor a perfect square on the left side: (s + 2)(s + 2) = -17 Can't calculate square root of the right side. The solution to this equation could not be determined.
