Simplifying 12s2 + -3.0s + 2.25 = 0 Reorder the terms: 2.25 + -3.0s + 12s2 = 0 Solving 2.25 + -3.0s + 12s2 = 0 Solving for variable 's'. Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. 0.1875 + -0.25s + s2 = 0 Move the constant term to the right: Add '-0.1875' to each side of the equation. 0.1875 + -0.25s + -0.1875 + s2 = 0 + -0.1875 Reorder the terms: 0.1875 + -0.1875 + -0.25s + s2 = 0 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + -0.25s + s2 = 0 + -0.1875 -0.25s + s2 = 0 + -0.1875 Combine like terms: 0 + -0.1875 = -0.1875 -0.25s + s2 = -0.1875 The s term is -0.25s. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25s + 0.015625 + s2 = -0.1875 + 0.015625 Reorder the terms: 0.015625 + -0.25s + s2 = -0.1875 + 0.015625 Combine like terms: -0.1875 + 0.015625 = -0.171875 0.015625 + -0.25s + s2 = -0.171875 Factor a perfect square on the left side: (s + -0.125)(s + -0.125) = -0.171875 Can't calculate square root of the right side. The solution to this equation could not be determined.
