Subproblem 1

Set the factor '(-27 + -24t + 4t2)' equal to zero and attempt to solve: Simplifying -27 + -24t + 4t2 = 0 Solving -27 + -24t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -6.75 + -6t + t2 = 0 Move the constant term to the right: Add '6.75' to each side of the equation. -6.75 + -6t + 6.75 + t2 = 0 + 6.75 Reorder the terms: -6.75 + 6.75 + -6t + t2 = 0 + 6.75 Combine like terms: -6.75 + 6.75 = 0.00 0.00 + -6t + t2 = 0 + 6.75 -6t + t2 = 0 + 6.75 Combine like terms: 0 + 6.75 = 6.75 -6t + t2 = 6.75 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 = 6.75 + 9 Reorder the terms: 9 + -6t + t2 = 6.75 + 9 Combine like terms: 6.75 + 9 = 15.75 9 + -6t + t2 = 15.75 Factor a perfect square on the left side: (t + -3)(t + -3) = 15.75 Calculate the square root of the right side: 3.968626967 Break this problem into two subproblems by setting (t + -3) equal to 3.968626967 and -3.968626967.

Subproblem 1

t + -3 = 3.968626967 Simplifying t + -3 = 3.968626967 Reorder the terms: -3 + t = 3.968626967 Solving -3 + t = 3.968626967 Solving for variable 't'.
