Subproblem 1

Set the factor '(10 + -7t + 2t2)' equal to zero and attempt to solve: Simplifying 10 + -7t + 2t2 = 0 Solving 10 + -7t + 2t2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 5 + -3.5t + t2 = 0 Move the constant term to the right: Add '-5' to each side of the equation. 5 + -3.5t + -5 + t2 = 0 + -5 Reorder the terms: 5 + -5 + -3.5t + t2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -3.5t + t2 = 0 + -5 -3.5t + t2 = 0 + -5 Combine like terms: 0 + -5 = -5 -3.5t + t2 = -5 The t term is -3.5t. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5t + 3.0625 + t2 = -5 + 3.0625 Reorder the terms: 3.0625 + -3.5t + t2 = -5 + 3.0625 Combine like terms: -5 + 3.0625 = -1.9375 3.0625 + -3.5t + t2 = -1.9375 Factor a perfect square on the left side: (t + -1.75)(t + -1.75) = -1.9375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
