Subproblem 1

Set the factor '(-5 + 10t + -2t2)' equal to zero and attempt to solve: Simplifying -5 + 10t + -2t2 = 0 Solving -5 + 10t + -2t2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 2.5 + -5t + t2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -5t + -2.5 + t2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -5t + t2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -5t + t2 = 0 + -2.5 -5t + t2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -5t + t2 = -2.5 The t term is -5t. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5t + 6.25 + t2 = -2.5 + 6.25 Reorder the terms: 6.25 + -5t + t2 = -2.5 + 6.25 Combine like terms: -2.5 + 6.25 = 3.75 6.25 + -5t + t2 = 3.75 Factor a perfect square on the left side: (t + -2.5)(t + -2.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (t + -2.5) equal to 1.936491673 and -1.936491673.
