Simplifying 0 = 150t + 3 + -16t2 Reorder the terms: 0 = 3 + 150t + -16t2 Solving 0 = 3 + 150t + -16t2 Solving for variable 't'. Combine like terms: 0 + -3 = -3 -3 + -150t + 16t2 = 3 + 150t + -16t2 + -3 + -150t + 16t2 Reorder the terms: -3 + -150t + 16t2 = 3 + -3 + 150t + -150t + -16t2 + 16t2 Combine like terms: 3 + -3 = 0 -3 + -150t + 16t2 = 0 + 150t + -150t + -16t2 + 16t2 -3 + -150t + 16t2 = 150t + -150t + -16t2 + 16t2 Combine like terms: 150t + -150t = 0 -3 + -150t + 16t2 = 0 + -16t2 + 16t2 -3 + -150t + 16t2 = -16t2 + 16t2 Combine like terms: -16t2 + 16t2 = 0 -3 + -150t + 16t2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.1875 + -9.375t + t2 = 0 Move the constant term to the right: Add '0.1875' to each side of the equation. -0.1875 + -9.375t + 0.1875 + t2 = 0 + 0.1875 Reorder the terms: -0.1875 + 0.1875 + -9.375t + t2 = 0 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.0000 + -9.375t + t2 = 0 + 0.1875 -9.375t + t2 = 0 + 0.1875 Combine like terms: 0 + 0.1875 = 0.1875 -9.375t + t2 = 0.1875 The t term is -9.375t. Take half its coefficient (-4.6875). Square it (21.97265625) and add it to both sides. Add '21.97265625' to each side of the equation. -9.375t + 21.97265625 + t2 = 0.1875 + 21.97265625 Reorder the terms: 21.97265625 + -9.375t + t2 = 0.1875 + 21.97265625 Combine like terms: 0.1875 + 21.97265625 = 22.16015625 21.97265625 + -9.375t + t2 = 22.16015625 Factor a perfect square on the left side: (t + -4.6875)(t + -4.6875) = 22.16015625 Calculate the square root of the right side: 4.707457514 Break this problem into two subproblems by setting (t + -4.6875) equal to 4.707457514 and -4.707457514.Subproblem 1
t + -4.6875 = 4.707457514 Simplifying t + -4.6875 = 4.707457514 Reorder the terms: -4.6875 + t = 4.707457514 Solving -4.6875 + t = 4.707457514 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '4.6875' to each side of the equation. -4.6875 + 4.6875 + t = 4.707457514 + 4.6875 Combine like terms: -4.6875 + 4.6875 = 0.0000 0.0000 + t = 4.707457514 + 4.6875 t = 4.707457514 + 4.6875 Combine like terms: 4.707457514 + 4.6875 = 9.394957514 t = 9.394957514 Simplifying t = 9.394957514Subproblem 2
t + -4.6875 = -4.707457514 Simplifying t + -4.6875 = -4.707457514 Reorder the terms: -4.6875 + t = -4.707457514 Solving -4.6875 + t = -4.707457514 Solving for variable 't'.
