Simplifying 0 = -8t2 + 75t + 1800 Reorder the terms: 0 = 1800 + 75t + -8t2 Solving 0 = 1800 + 75t + -8t2 Solving for variable 't'. Combine like terms: 0 + -1800 = -1800 -1800 + -75t + 8t2 = 1800 + 75t + -8t2 + -1800 + -75t + 8t2 Reorder the terms: -1800 + -75t + 8t2 = 1800 + -1800 + 75t + -75t + -8t2 + 8t2 Combine like terms: 1800 + -1800 = 0 -1800 + -75t + 8t2 = 0 + 75t + -75t + -8t2 + 8t2 -1800 + -75t + 8t2 = 75t + -75t + -8t2 + 8t2 Combine like terms: 75t + -75t = 0 -1800 + -75t + 8t2 = 0 + -8t2 + 8t2 -1800 + -75t + 8t2 = -8t2 + 8t2 Combine like terms: -8t2 + 8t2 = 0 -1800 + -75t + 8t2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -225 + -9.375t + t2 = 0 Move the constant term to the right: Add '225' to each side of the equation. -225 + -9.375t + 225 + t2 = 0 + 225 Reorder the terms: -225 + 225 + -9.375t + t2 = 0 + 225 Combine like terms: -225 + 225 = 0 0 + -9.375t + t2 = 0 + 225 -9.375t + t2 = 0 + 225 Combine like terms: 0 + 225 = 225 -9.375t + t2 = 225 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 = 225 + 21.97265625 Reorder the terms: 21.97265625 + -9.375t + t2 = 225 + 21.97265625 Combine like terms: 225 + 21.97265625 = 246.97265625 21.97265625 + -9.375t + t2 = 246.97265625 Factor a perfect square on the left side: (t + -4.6875)(t + -4.6875) = 246.97265625 Calculate the square root of the right side: 15.715363701 Break this problem into two subproblems by setting (t + -4.6875) equal to 15.715363701 and -15.715363701.Subproblem 1
t + -4.6875 = 15.715363701 Simplifying t + -4.6875 = 15.715363701 Reorder the terms: -4.6875 + t = 15.715363701 Solving -4.6875 + t = 15.715363701 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 = 15.715363701 + 4.6875 Combine like terms: -4.6875 + 4.6875 = 0.0000 0.0000 + t = 15.715363701 + 4.6875 t = 15.715363701 + 4.6875 Combine like terms: 15.715363701 + 4.6875 = 20.402863701 t = 20.402863701 Simplifying t = 20.402863701Subproblem 2
t + -4.6875 = -15.715363701 Simplifying t + -4.6875 = -15.715363701 Reorder the terms: -4.6875 + t = -15.715363701 Solving -4.6875 + t = -15.715363701 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 = -15.715363701 + 4.6875 Combine like terms: -4.6875 + 4.6875 = 0.0000 0.0000 + t = -15.715363701 + 4.6875 t = -15.715363701 + 4.6875 Combine like terms: -15.715363701 + 4.6875 = -11.027863701 t = -11.027863701 Simplifying t = -11.027863701Solution
