Simplifying -2t2 + 12t + 9 = 28 Reorder the terms: 9 + 12t + -2t2 = 28 Solving 9 + 12t + -2t2 = 28 Solving for variable 't'. Reorder the terms: 9 + -28 + 12t + -2t2 = 28 + -28 Combine like terms: 9 + -28 = -19 -19 + 12t + -2t2 = 28 + -28 Combine like terms: 28 + -28 = 0 -19 + 12t + -2t2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 9.5 + -6t + t2 = 0 Move the constant term to the right: Add '-9.5' to each side of the equation. 9.5 + -6t + -9.5 + t2 = 0 + -9.5 Reorder the terms: 9.5 + -9.5 + -6t + t2 = 0 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + -6t + t2 = 0 + -9.5 -6t + t2 = 0 + -9.5 Combine like terms: 0 + -9.5 = -9.5 -6t + t2 = -9.5 The t term is -6t. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6t + 9 + t2 = -9.5 + 9 Reorder the terms: 9 + -6t + t2 = -9.5 + 9 Combine like terms: -9.5 + 9 = -0.5 9 + -6t + t2 = -0.5 Factor a perfect square on the left side: (t + -3)(t + -3) = -0.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
