Simplifying -5t2 + 12t + -9 = 0 Reorder the terms: -9 + 12t + -5t2 = 0 Solving -9 + 12t + -5t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 1.8 + -2.4t + t2 = 0 Move the constant term to the right: Add '-1.8' to each side of the equation. 1.8 + -2.4t + -1.8 + t2 = 0 + -1.8 Reorder the terms: 1.8 + -1.8 + -2.4t + t2 = 0 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + -2.4t + t2 = 0 + -1.8 -2.4t + t2 = 0 + -1.8 Combine like terms: 0 + -1.8 = -1.8 -2.4t + t2 = -1.8 The t term is -2.4t. Take half its coefficient (-1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. -2.4t + 1.44 + t2 = -1.8 + 1.44 Reorder the terms: 1.44 + -2.4t + t2 = -1.8 + 1.44 Combine like terms: -1.8 + 1.44 = -0.36 1.44 + -2.4t + t2 = -0.36 Factor a perfect square on the left side: (t + -1.2)(t + -1.2) = -0.36 Can't calculate square root of the right side. The solution to this equation could not be determined.
