Subproblem 1

Set the factor 't2' equal to zero and attempt to solve: Simplifying t2 = 0 Solving t2 = 0 Move all terms containing t to the left, all other terms to the right. Simplifying t2 = 0 Take the square root of each side: t = {0}

Subproblem 2

Set the factor '(9 + 2t + -5t2)' equal to zero and attempt to solve: Simplifying 9 + 2t + -5t2 = 0 Solving 9 + 2t + -5t2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.8 + -0.4t + t2 = 0 Move the constant term to the right: Add '1.8' to each side of the equation. -1.8 + -0.4t + 1.8 + t2 = 0 + 1.8 Reorder the terms: -1.8 + 1.8 + -0.4t + t2 = 0 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + -0.4t + t2 = 0 + 1.8 -0.4t + t2 = 0 + 1.8 Combine like terms: 0 + 1.8 = 1.8 -0.4t + t2 = 1.8 The t term is -0.4t. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4t + 0.04 + t2 = 1.8 + 0.04 Reorder the terms: 0.04 + -0.4t + t2 = 1.8 + 0.04 Combine like terms: 1.8 + 0.04 = 1.84 0.04 + -0.4t + t2 = 1.84 Factor a perfect square on the left side: (t + -0.2)(t + -0.2) = 1.84 Calculate the square root of the right side: 1.356465997 Break this problem into two subproblems by setting (t + -0.2) equal to 1.356465997 and -1.356465997.

Subproblem 1
