Simplifying s2 + 3s + 4 = 0 Reorder the terms: 4 + 3s + s2 = 0 Solving 4 + 3s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + 3s + -4 + s2 = 0 + -4 Reorder the terms: 4 + -4 + 3s + s2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 3s + s2 = 0 + -4 3s + s2 = 0 + -4 Combine like terms: 0 + -4 = -4 3s + s2 = -4 The s term is 3s. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3s + 2.25 + s2 = -4 + 2.25 Reorder the terms: 2.25 + 3s + s2 = -4 + 2.25 Combine like terms: -4 + 2.25 = -1.75 2.25 + 3s + s2 = -1.75 Factor a perfect square on the left side: (s + 1.5)(s + 1.5) = -1.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
