Simplifying 50 = -16t2 + 100t Reorder the terms: 50 = 100t + -16t2 Solving 50 = 100t + -16t2 Solving for variable 't'. Reorder the terms: 50 + -100t + 16t2 = 100t + -100t + -16t2 + 16t2 Combine like terms: 100t + -100t = 0 50 + -100t + 16t2 = 0 + -16t2 + 16t2 50 + -100t + 16t2 = -16t2 + 16t2 Combine like terms: -16t2 + 16t2 = 0 50 + -100t + 16t2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(25 + -50t + 8t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(25 + -50t + 8t2)' equal to zero and attempt to solve: Simplifying 25 + -50t + 8t2 = 0 Solving 25 + -50t + 8t2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 3.125 + -6.25t + t2 = 0 Move the constant term to the right: Add '-3.125' to each side of the equation. 3.125 + -6.25t + -3.125 + t2 = 0 + -3.125 Reorder the terms: 3.125 + -3.125 + -6.25t + t2 = 0 + -3.125 Combine like terms: 3.125 + -3.125 = 0.000 0.000 + -6.25t + t2 = 0 + -3.125 -6.25t + t2 = 0 + -3.125 Combine like terms: 0 + -3.125 = -3.125 -6.25t + t2 = -3.125 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 = -3.125 + 9.765625 Reorder the terms: 9.765625 + -6.25t + t2 = -3.125 + 9.765625 Combine like terms: -3.125 + 9.765625 = 6.640625 9.765625 + -6.25t + t2 = 6.640625 Factor a perfect square on the left side: (t + -3.125)(t + -3.125) = 6.640625 Calculate the square root of the right side: 2.576941016 Break this problem into two subproblems by setting (t + -3.125) equal to 2.576941016 and -2.576941016.Subproblem 1
