Subproblem 1

Set the factor '(10 + 25t + 4t2)' equal to zero and attempt to solve: Simplifying 10 + 25t + 4t2 = 0 Solving 10 + 25t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2.5 + 6.25t + t2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 6.25t + -2.5 + t2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 6.25t + t2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 6.25t + t2 = 0 + -2.5 6.25t + t2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 6.25t + t2 = -2.5 The t term is 6.25t. Take half its coefficient (3.125). Square it (9.765625) and add it to both sides. Add '9.765625' to each side of the equation. 6.25t + 9.765625 + t2 = -2.5 + 9.765625 Reorder the terms: 9.765625 + 6.25t + t2 = -2.5 + 9.765625 Combine like terms: -2.5 + 9.765625 = 7.265625 9.765625 + 6.25t + t2 = 7.265625 Factor a perfect square on the left side: (t + 3.125)(t + 3.125) = 7.265625 Calculate the square root of the right side: 2.695482332 Break this problem into two subproblems by setting (t + 3.125) equal to 2.695482332 and -2.695482332.

Subproblem 1
