Simplifying -1s2 + 4s + -24 = 0 Reorder the terms: -24 + 4s + -1s2 = 0 Solving -24 + 4s + -1s2 = 0 Solving for variable 's'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 24 + -4s + s2 = 0 Move the constant term to the right: Add '-24' to each side of the equation. 24 + -4s + -24 + s2 = 0 + -24 Reorder the terms: 24 + -24 + -4s + s2 = 0 + -24 Combine like terms: 24 + -24 = 0 0 + -4s + s2 = 0 + -24 -4s + s2 = 0 + -24 Combine like terms: 0 + -24 = -24 -4s + s2 = -24 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 = -24 + 4 Reorder the terms: 4 + -4s + s2 = -24 + 4 Combine like terms: -24 + 4 = -20 4 + -4s + s2 = -20 Factor a perfect square on the left side: (s + -2)(s + -2) = -20 Can't calculate square root of the right side. The solution to this equation could not be determined.
