Simplifying 3X2 = -9X + -25.5 Reorder the terms: 3X2 = -25.5 + -9X Solving 3X2 = -25.5 + -9X Solving for variable 'X'. Reorder the terms: 25.5 + 9X + 3X2 = -25.5 + -9X + 25.5 + 9X Reorder the terms: 25.5 + 9X + 3X2 = -25.5 + 25.5 + -9X + 9X Combine like terms: -25.5 + 25.5 = 0.0 25.5 + 9X + 3X2 = 0.0 + -9X + 9X 25.5 + 9X + 3X2 = -9X + 9X Combine like terms: -9X + 9X = 0 25.5 + 9X + 3X2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 8.5 + 3X + X2 = 0 Move the constant term to the right: Add '-8.5' to each side of the equation. 8.5 + 3X + -8.5 + X2 = 0 + -8.5 Reorder the terms: 8.5 + -8.5 + 3X + X2 = 0 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + 3X + X2 = 0 + -8.5 3X + X2 = 0 + -8.5 Combine like terms: 0 + -8.5 = -8.5 3X + X2 = -8.5 The X term is 3X. 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. 3X + 2.25 + X2 = -8.5 + 2.25 Reorder the terms: 2.25 + 3X + X2 = -8.5 + 2.25 Combine like terms: -8.5 + 2.25 = -6.25 2.25 + 3X + X2 = -6.25 Factor a perfect square on the left side: (X + 1.5)(X + 1.5) = -6.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
