Set the factor 't' equal to zero and attempt to solve: Simplifying t = 0 Solving t = 0 Move all terms containing t to the left, all other terms to the right. Simplifying t = 0

Subproblem 2

Set the factor '(-36 + 3t + 4t2)' equal to zero and attempt to solve: Simplifying -36 + 3t + 4t2 = 0 Solving -36 + 3t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -9 + 0.75t + t2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + 0.75t + 9 + t2 = 0 + 9 Reorder the terms: -9 + 9 + 0.75t + t2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 0.75t + t2 = 0 + 9 0.75t + t2 = 0 + 9 Combine like terms: 0 + 9 = 9 0.75t + t2 = 9 The t term is 0.75t. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75t + 0.140625 + t2 = 9 + 0.140625 Reorder the terms: 0.140625 + 0.75t + t2 = 9 + 0.140625 Combine like terms: 9 + 0.140625 = 9.140625 0.140625 + 0.75t + t2 = 9.140625 Factor a perfect square on the left side: (t + 0.375)(t + 0.375) = 9.140625 Calculate the square root of the right side: 3.023346656 Break this problem into two subproblems by setting (t + 0.375) equal to 3.023346656 and -3.023346656.

Subproblem 1

t + 0.375 = 3.023346656 Simplifying t + 0.375 = 3.023346656 Reorder the terms: 0.375 + t = 3.023346656 Solving 0.375 + t = 3.023346656 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + t = 3.023346656 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + t = 3.023346656 + -0.375 t = 3.023346656 + -0.375 Combine like terms: 3.023346656 + -0.375 = 2.648346656 t = 2.648346656 Simplifying t = 2.648346656

Subproblem 2

t + 0.375 = -3.023346656 Simplifying t + 0.375 = -3.023346656 Reorder the terms: 0.375 + t = -3.023346656 Solving 0.375 + t = -3.023346656 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + t = -3.023346656 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + t = -3.023346656 + -0.375 t = -3.023346656 + -0.375 Combine like terms: -3.023346656 + -0.375 = -3.398346656 t = -3.398346656 Simplifying t = -3.398346656
