Subproblem 1

Set the factor '(-3 + 6t + 4t2)' equal to zero and attempt to solve: Simplifying -3 + 6t + 4t2 = 0 Solving -3 + 6t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.75 + 1.5t + t2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + 1.5t + 0.75 + t2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + 1.5t + t2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + 1.5t + t2 = 0 + 0.75 1.5t + t2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 1.5t + t2 = 0.75 The t term is 1.5t. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5t + 0.5625 + t2 = 0.75 + 0.5625 Reorder the terms: 0.5625 + 1.5t + t2 = 0.75 + 0.5625 Combine like terms: 0.75 + 0.5625 = 1.3125 0.5625 + 1.5t + t2 = 1.3125 Factor a perfect square on the left side: (t + 0.75)(t + 0.75) = 1.3125 Calculate the square root of the right side: 1.145643924 Break this problem into two subproblems by setting (t + 0.75) equal to 1.145643924 and -1.145643924.

Subproblem 1
