Simplifying -16t2 + 32t + 382 = 0 Reorder the terms: 382 + 32t + -16t2 = 0 Solving 382 + 32t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '2'. 2(191 + 16t + -8t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(191 + 16t + -8t2)' equal to zero and attempt to solve: Simplifying 191 + 16t + -8t2 = 0 Solving 191 + 16t + -8t2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -23.875 + -2t + t2 = 0 Move the constant term to the right: Add '23.875' to each side of the equation. -23.875 + -2t + 23.875 + t2 = 0 + 23.875 Reorder the terms: -23.875 + 23.875 + -2t + t2 = 0 + 23.875 Combine like terms: -23.875 + 23.875 = 0.000 0.000 + -2t + t2 = 0 + 23.875 -2t + t2 = 0 + 23.875 Combine like terms: 0 + 23.875 = 23.875 -2t + t2 = 23.875 The t term is -2t. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2t + 1 + t2 = 23.875 + 1 Reorder the terms: 1 + -2t + t2 = 23.875 + 1 Combine like terms: 23.875 + 1 = 24.875 1 + -2t + t2 = 24.875 Factor a perfect square on the left side: (t + -1)(t + -1) = 24.875 Calculate the square root of the right side: 4.987484336 Break this problem into two subproblems by setting (t + -1) equal to 4.987484336 and -4.987484336.Subproblem 1
t + -1 = 4.987484336 Simplifying t + -1 = 4.987484336 Reorder the terms: -1 + t = 4.987484336 Solving -1 + t = 4.987484336 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + t = 4.987484336 + 1 Combine like terms: -1 + 1 = 0 0 + t = 4.987484336 + 1 t = 4.987484336 + 1 Combine like terms: 4.987484336 + 1 = 5.987484336 t = 5.987484336 Simplifying t = 5.987484336Subproblem 2
t + -1 = -4.987484336 Simplifying t + -1 = -4.987484336 Reorder the terms: -1 + t = -4.987484336 Solving -1 + t = -4.987484336 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + t = -4.987484336 + 1 Combine like terms: -1 + 1 = 0 0 + t = -4.987484336 + 1 t = -4.987484336 + 1 Combine like terms: -4.987484336 + 1 = -3.987484336 t = -3.987484336 Simplifying t = -3.987484336Solution
